Unity asyncgpureadback android Think Splatoon but for Unity’s terrain. 0. RequestIntoNativeArray causes InvalidOperationException on NativeArray Visual Effects-Nov 26, 2020 How to reproduce: 1. Note that there is a trade-off between performance and latency. What I’m doing is downloading 600x600xARGBfloat from a compute shader, I think a argbfloat is 4 bytes so that’s 1MB Are If your texture resides on the GPU (RenderTexture), you have to bring the data back to the CPU (Texture2D) before you can write to disk, and this can be done in a variety of ways: using ReadPixels, using AsyncGPUReadback, etc you might also want to crop the image, which these methods allow. We’re excited to announce that starting with Unity 2023. ReadPixels is unfortunately very slow, causing lag in the simulation. float4 clipPos = UnityWorldToClipPos(p); depth = clipPos. Call AsyncGPUReadback. Hi, thank you for your reply. Experimental. So probably what you are seeing with it not working, \$\begingroup\$ What Unity version are you using? There was a bug where Unity would incorrectly dispose of a NativeArray, but the issue tracker reports this as fixed in 2020. I dispatch the compute shader and I want to return the data once the process is finished. com/threads/graphics-asynchronous-gpu-readback-api. I want to implement a lens flare effect for a 3D mobile project (Android, iOS). So if you have a RenderTexture with 7 mipmaps, you have to create 7 AsyncGPUReadBack calls, and track 7 different AsyncGPUReadBackRequests for that texture. For example, it tends to not update without window focus. This feature is really useful for screenshot or network stream of a game camera because we need AsyncGPUReadback. Request. GetPixelsexcept it does not Dear Unity3d experts, I have a question regarding ComputeShaders with multiple kernels and one ComputeBuffer. Player settings: 1490×2044 316 Sometimes things happen with Unity development, bugs and limitations are far from ideal situations that I might moan at Unity about. WaitAllRequests Leave feedback Suggest a change Success! Thank you for helping us improve the quality of Unity Documentation. MTRendering, PlayerSettings. I’m doing a lot of those requests, so I’m wondering if I’m calling it too much concurrently. 0 (and later) and GL core. My project does a lot of procedural generation and caching the textures for hundreds of different instances will save gobbles of memory and gpu perf. We tested with an otherwise empty project with a tiny script that starts a task and reports debug logs in and out of it, and also attempt to get certain properties like Use AsyncGPUReadback. request = AsyncGPUReadback. The problem is that they are ints, making them long large enough to Hello everyone. In the script, I create a Texture2D and copy current frame image from the Textures and samplers aren’t separate objects in Unity, so to use them in compute shaders you must follow one of the following Unity-specific rules: Use the same name as the Texture name, with sampler at the beginning (for example, Texture2D MyTex ; SamplerState samplerMyTex ). Although we cannot accept all submissions, we do read each suggested change from Thank you for helping us improve the quality of Unity Documentation. We don’t need to know this every frame; currently we’re checking every 0. 1. I stumbled upon this class, AsyncGPUReadback, which could fit my needs. Submission AsyncGPUReadback. What am I doing wrong? I tried many different texture formats but nothing seems to change the color offset. GetData()) but I can’t get it working using the new AsyncGPUReadback requests. I use AsyncGpuReadback to execute a callback when its ready. C#; Scripting API. I’ve tried comparing this to the new AsyncGPUReadback. 0a9 Issue ID UUM-7340 Regression No Array is marked as undisposable when using I’m guessing you’re asking this because you’re trying to avoid a ReadPixels() for getting the texture data in C#. RequestAsync Leave feedback Suggest a change Success! Thank you for helping us improve the quality of Unity Documentation. CoreModule Leave feedback Suggest a change Success! Thank you for helping us improve the quality of Unity Documentation. RequestIntoNativeArray() make an internal copy of the texture before it I am getting errors like “The type or namespace name ‘AsyncGPUReadbackRequest’ could not be found (are you missing a using directive or an assembly reference?)” “The name ‘AsyncGPUReadback’ does not exist in the current context” Although I have included using UnityEngine. I actually got some help elsewhere and found a Solution by using AsyncGPUReadbackRequest I would like to obtain the average color of my main camera render in order to, among other things, dim the user interface in dark areas and vice versa for light area. toarray() ,This method is time-consuming. Rendering / Implemented in:UnityEngine. ) Set it as target for a Camera and then do the ReadPixels part after the Camera is done rendering. Is something described here not working as you expect it to? I am using AsyncGPUReadback to retrieve the contents of a Compute Buffer each frame, it sometimes works, but equally sometimes the request completes with “hasError” set. I’m attempting to use AsyncGPUReadback as part of an editor tool. CoreModule Other Versions Leave feedback Suggest a change Success! Thank you for helping us improve the quality of Unity Documentation. Either get a completely black image or an image with a black line as attached below. But WaitForCompletion can only be called on the main thread, and it may hang up the thread for a while. I do not need the image immediately, so being able to read back the 2021. WaitAllRequests. Leave feedback. 1. ReadPixels() due to performance reasons. 2 was introduced a really neat feature: being able get a frame from the gpu to the cpu without blocking the rendering. After 15 seconds, my unity instance was consuming more than 8GB of memory. When the app loads press on "Scratch here" box AsyncGPUReadback. AsyncGPUReadback,AsyncGPUReadbackRequest. Request for that, however, the callback provided never gets executed. Request(renderTexture), and while this works great in the editor and in a standalone windows build, it does not work on a WebGL build. GetPixel to get three pixels (or more with a precision setting) on screen and then average these over multiple frames, but in order to do that I’d need the render texture of the I want to read a texture into a native array. Using 2021. Unity 2021. ) I achieved: Splitting the Compute-Shader into smaller pieces, so I can do multiple Thanks for your response! I have tried that or similar. Although we Close AsyncGPUReadback. 5; and the depth buffer was 0. 1 is a regression regarding the AsyncGPUReadBack Requests where the memory is never released causing a rather considerable amount of ram per frame to be accumulated. The NatCam API provides access to device camera functions like high resolution previews (at high frame rates), exposure, focusing, zooming, flash, tor throw new ArgumentException("AsyncGPUReadback cannot use Temp memory as input since the result may only become available at an unspecified point in the future. What I’ve been working on requires me to occasionally know what color the painted terrain is. 0f1 and also experiencing similar issues, But I found it may go deeper than this alone. As you can see in the image below the background is b&w and the patterns will change and distort during the game (as crazy as possible). You can use an async method that waits for the request to finish and then does something with the result once ready instead of stalling the main thread until the request is done. . WaitForCompletion is a very odd beast, as when you call it can be be quick, or take a long This Unity sample project shows how to use the asynchronous GPU readback API to capture render outputs without blocking the main thread. Hi, i am using an nVidia GTX 750 Ti with full DX11/12 support and unity 5. This function is similar to Texture2D. For some reason your suggested change could not be submitted. If my compute shader takes 50ms to AsyncGPUReadback. This class is used to copy resource data from the GPU to the CPU without any stall (GPU or CPU), but adds a few frames of latency. Is it possible to request AsyncGPUReadback each frame Unity Discussions I’m new to HDRP and Unity in general and am struggling to actually fetching the depth data from the camera render texture into anything i can store in a texture2D and transmit it. Request with Jint in JavaScript also, but mainly just in C#, to make a basic screenshot without the use of IEnumerable or yield We’ve got a painting application, and we frequently need to know the current color under the brush. So if you have a RenderTexture with 7 mipmaps, you have to create 7 AsyncGPUReadBack calls, Hey guys, I’d love to get AsyncGPUReadback. 4. 0f1c1) Any hints on what is wrong with this setup? Editor Window using UnityEngine; using AsyncGPUReadback. Success! Thank you for helping us improve the quality of Unity Documentation. Request Make a direct request for the relevant data instead of copying it into the CPU side of a RT. 2 I have created a system that paints terrain in play mode. I just tested my project on that version and gain a massive performance increase in Android getting rid of ReadPixel code. 14. 0b14 2022. 5 for the pixels covered by the geometry. You have 2 options: Use GetData and copy into NativeArray afterwards Use Unity - Scripting API: AsyncGPUReadback, which also copies the data back from the GPU, but does it asynchronously. but I have no way to solve it. IO; using UnityEngine; using UnityEngine. done (not every frame), there’s no errors. 1 (Oreo), EMUI 8 Introduced in 2020. class in UnityEngine. The player has two points and items only one point, this means I will have a Where does anything actually get rendered to the RenderTexture? (You’re setting it as active and immediately reading from it. GetData(). Pending requests are automatically updated each frame. AsyncGPUReadback. The Editor should update its GUI meanwhile for several reasons. The project does not use Unity’s physics engine. z / clipPos. graphicsJobs and PlayerSettings. done property in an Update loop. Request” after every render in one frame. The image sometimes shows completely black and sometimes as below randomly, with the black area changing in AsyncGPUReadback. GetData<> behaves weirdly depending on the data type. dstFormat The target TextureFormat of the data. This repo is heavily based on Alabate's great work, also added function to read compute buffer. (VideoPlayerWithOpenCVForUnityExample) Import At least in Unity 2020. active = renderTexture1; I’m getting random crashes on iPad that I think are related to AsyncGPUReadbackRequest. Although we Hi @sstrong, You need to use RenderTexture with dimension parameter configured to tex2DArray and in your compute shader use RWTexture2DArray. You can’t bypass this step. Although we cannot accept all submissions, we do read each suggested change from our users and will make Additional resources:AsyncGPUReadback. It tries to match the AsyncGPUReadback is "asynchronous", meaning that the result is available at some point in the future, rather than immediately. UPDATE: In another thread the Unity team acknowledged this is a bug and has been fixed, but is being backported to 2021. I played around a lot and came to the conclusion, that this doesn’t work as I intended it. Please <a>try again</a> in a few minutes. I’m using a NativeArray in an effort to reduce recurring garbage allocations. But it doesn’t help, AsyncGPUReadback still takes 35ms every time. IsFormatSupported. Since the API is based around updates – which operate differently in edit mode versus play mode – I’m not sure of the correct way to use it. ReadbackImage instead of the newer Unity - Scripting API: AsyncGPUReadback 4723502--446987--upload_2019-7-8_9-34-48. Instead of calling it once and waiting for the result I want to call it multiple times per frame (while modifying the buffer with compute shaders in between), and then process the results as they arrive. 0) Language English C# Scripting API Version: Unity 6 Language English OpenGLESVersion enumeration Leave feedback Suggest a change Success! Thank you for helping us improve the quality of Unity Documentation. mipIndex The index of the mipmap to fetch. The result is accessible only for a I’ve been trying to actually use Unity’s AsyncGPUReadback. Use AsyncGPUReadback. Rendering; using UnityEngine. Had some legacy code running fine on Quest 2 + OpenGL + BRP, but getting strange artifacts when I try to ReadPixel and save an image. In your example, you check that there was I'm trying to use AsyncGPUReadback to get data from the meshes of a GameObject instantiated from a bundle, but I keep getting the following error. Render() to an RT + GetPixels every time I needed a refresh but obviously this would be too slow for a high framerate (target is around 60 Hello, Is there a way to quickly send color images from a camera in Unity in a ROS2 message? Currently, I am using a rendertexture to capture from a camera, using readpixels to get a texture2d, then using GetRawTextureData to get the raw byte data. I thought of using Texture2D. 0) Language English. \$\endgroup\$ – Hi, I have an 1,073,741,824 element compute buffer with a stride of 4 (4,294,967,296 bytes), the GetData api works fine with it because the offset and count parameters are passed as index counts, but with AsyncGPUReadback the offset and count parameters are passed as bytes. 7 Hi, I’m currently using AsyncGPUReadback. I got everything to work like I want it to, but it seems like I’m still doing something wrong with the NativeArray I’m I know, odd question, but the purpose of AsyncGPUReadback is to offset something on the GPU. Compute shader : RWStructuredBuffer vertexBuffer; Thank you for helping us improve the quality of Unity Documentation. RequestIntoNativeArray(ref NativeArray_1, ComputeBuffer) Leave feedback.

Request(source,0,TextureFormat. 529901/#post-3487735). Conversion happens automatically if this format is different from the format I’m using Unity 2019. Request Because it’s async, it won’t cause a stall in your frame while reading back the texture. Request() after the last Kernel is done. Is there another way to get the output of public static class AsyncGPUReadback Methods | Improve this Doc View Source Request(ComputeBuffer, Action<AsyncGPUReadbackRequest>) Declaration public static AsyncGPUReadbackRequest Request(ComputeBuffer src, Action Parameters Type <> GetData is pulling data back to the CPU, from the GPU memory. I’m using Unity 2021. As far as I know now, this approach doesn’t bring the data from GPU to CPU within Unity, explaining why the in ios there is only one folder for pictures and videos but in android there are multiple folders can I create a folder with my apps name and save it in there with NatShare. Note that the compute shader really doesn’t generate any important data. RequestIntoNativeArray working, as streaming the data from my compute shader directly into a native array would just be beautiful. 32f1 2021. png 1194×123 17. 3, the Unity Web Player now provides experimental support for the new Hey guys! I’m trying to create a simple game about colors and I need to read some points on the screen and check the color these points are hovering. Entities, com_unity_entities. (We didn’t try on iPhone and Android) Environment: Unity version: 2019. Everything works fine with previous method (using buffer. It's only applicable when a Hello all ! I’d like to read the color under the cursor of the mouse in game. Although we cannot accept all submissions, we do read each suggested change from our users and AsyncGPUReadback. 6 to 2017.

Although we cannot accept all submissions, we do read each suggested change from our users and will make Unity Discussions NatCorder - Video Recording API. Can you please tell me So I think my problem is that I have too many calls of “Camera. My goal is to use those colors as lighting effect of a video screen in a scene. However, it has some limits that seriously complicate the process immensely. Request to retrieve an asynchronous request for a GPU resource. I have a private property Native array that AsyncGPUReadback in Unity is a feature that allows developers to copy data, such as a specific pixel's color, from textures on the GPU to code on the CPU. Support was added in Unity 2021. RequestIntoNativeArrayAsync. Render()” followed by “AsyncGPUReadback. I wanted to test SetHeightsDelayLOD because it’s faster than SetHeights. My Situation: I want to get a Compute-Shader run in Edit-Mode. It’s great when a gpu takes too long to finish a task, but no matter how quick and simple the shader is I can’t seem to be able to fetch data and request more during the same frame; at best I can only get a result every other frame. My initial setup was to manually call Camera. X, and 2022. I have a camera rendering to a RenderTexture that is 64px by 64px, or 4096 total pixels. "); var nativeArrayData = new AsyncRequestNativeArrayData(); AsyncGPUReadback. TryGetLatestCPUImage reads the image back immediately, which is quite bad for performance. I need to pull data from the GPU to the CPU without blocking my main thread. Graphics: Added support for async readback when using OpenGL ES 3. Although we cannot accept all submissions, we do read each suggested change from our users and will output Reference to a NativeArray to write the data into. 3, we have observed that tasks in Android do trigger new threads by default. I’m disapointed by the result I am getting from the async function, it’s possible that I do it wrong but then what’s the right way? Async is on the right, the old way is on the left and the result updates at the same speed. I need RGBs to write stdin. RequestAsync. (128x128 res, Unity 2020. 0) Language English C# Scripting API Version: Unity 6 Preview Language English NativeArray<T0>. src The resource to read the data from. RequestIntoNativeArray was rejected, but it seems like the reason for it was that Unity thinks this issue only happens with arrays such that a async readback was requested multiple times in a single frame, however this issue still happens even I have a setup like the following, where I compute a 65*65 array of Vector3 in a compute shader. THANK YOU. RequestIntoNativeArray - What am I doing wrong? The RenderTextureをPNGに保存（AsyncGPUReadback利用） Unity; Last updated at 2022-09-20 Posted at 2022-09-12. So if a project were calling ReadData, it wouldn’t work. So far so good. 7f On Windows 10 On MacOS 10. SystemInfo. Submission failed. Seems, that the webcamTexture. The current setup usually runs for like a minute before the new texture is created in the project. I’m using a NativeArray in an effort to reduce recurring Version: Unity 6 (6000. I just tested this with WebGPU, I made a shader with out float depth : SV_Depth, and set depth = 0. AsyncGPUReadback. w; @Cleverlie There’s no limitation for writing to the depth buffer via SV_Depth. After startup, you can use the property SystemInfo. RequestIntoNativeSlice. The callback converts the return data to a Color array. RequestIntoNativeArray. Version: Unity 6. zip (574 KB) Unity Discussions Getting a render texture byte[] using Appears like the issue in Unity Issue Tracker - InvalidOperationException when using AsyncGPUReadback. Open the “Frame_Count_Bug” project 2. X @richardkettlewell thanks for keeping an eye on this issue and hope you are returning from a well deserved holiday. The NativeArray you provide to RequestIntoNativeArray should not be disposed/invalidated by Unity - it should be yours for as long as you want it. Is this an expected side AsyncGPUReadback. unity. The result is accessible only for a single frame once is successfully fulfilled and this request is then disposed of in the following frame. I have a function that I call to blend layers. In my testing I’ve had the most success with this approach: public class MyWindow : EditorWindow { AsyncGPUReadbackRequest In a coroutine Job work AsyncGPUReadback works But when combined in a coroutine, separated by yield return WaitWhile() oh la la. This is also reproducible in 2020. In case if I request AsyncGPUReadback, only when the previous AsyncGPUReadbackRequest. I am doing image capture using AsyncGPUReadbackRequest using two different approaches, one for capturing the screen image and the other for capturing from a renderTexture. It will take 100+ milliseconds to get 4K textures,but other method is not time-consuming. (source: https://forum. Thanks for the information! Is this the fastest way or I can improve the performance? If I’m interpreting this correctly, I’m still getting a blocking Gfx. A related issue was reported by @jhelbig in this post: AsyncGPUReadback. So I was wondering if anyone got more luck with these and how they did it, pattern etc I am working on a computer vision application which requires me to read back the current camera image for processing. I’ve tried with both AsyncGPUReadback (prefered to not block the main thread) and ReadPixels, both work only Hi, I have a class that calculates mesh data in compute shader and does additional work in a Job. RGBA32); and deals with it on update Since Unity Technologies asked us to post our suggestions to the forum, here is my first feedback If I run our game on Android, it outputs: WARNING: RGBA Compressed BC7 sRGB format is not supported, decompressing texture WARNING: RGB Compressed DXT1 UNorm format is not supported, decompressing texture It would be enormously helpful if the Version: Unity 6 (6000.

How one can access a specific index of the array in Compute Shader let’s say i would AsyncGPUReadback how to take simple screenshot no ienumerable I’ve been trying to actually use Unity’s AsyncGPUReadback. Assertions; using UnityEngine. isReadable must be true, and you must call Apply after ReadPixels to upload the changed pixels to the GPU. On the editor and in my Windows Build it works fine, but on the Android Build (Tested on Oculus Quest 2) all values in the array are 0. Asset-Store-Assets. 9f1) What am I missing? Thanks 6667351–762949–UNITY_AsyncCaptureTest-master. Then read the data back to CPU-side with AsyncGPUReadback. Only the AsyncGPUReadback api can be used to read buffers and textures with WebGPU. Community Showcases. This feature is really useful for screenshot or network stream of a game camera because we need the frame on the cpu, but we don't care if there is a little de The best workaround I have come across is Unity's built-in async GPU readback functionality but unfortunately, since I am developing this for a VR application, the graphics API needs to be Allows the asynchronous read back of GPU resources. I am using Unity 2020. But now, after I have need to copy RenderTextures to Texture2D, and it has to be done quickly. WaitAllRequests(); Things that will cause the problem Hi! I am trying to read some pixels’ color from running video by Video Player. GetNativeTexturePtr(); returns a pointer indeed, but the data can’t be used directly in Unity for further usage. Compute() which is instant because Unity does not wait for it to finish. NatShare uses Android’s MediaStore API’s for saving items to the camera roll; we don’t manipulate files or folders. 6 seems to fix RequestIntoNativeArray in “one way”. Would be nice to have the main thread free while we wait for the GPU. However, getting the texture data from a RenderTexture AsyncGPUReadback. Now you don’t have to settle for the slow, lacking WebCamTexture API. graphicsJobMode, as well as the target platform capabilities decides the rendering threading mode during the start of the Unity Editor or Standalone. Who Using 2021. Although we cannot accept all submissions, we do read each suggested change from How to reproduce: 1.

Although we cannot accept all submissions, we do read each suggested change from our Close Hi, i need to create a render texture and set it as a Tex2DArrayto a compute shader and then work on every texture in the array. RequestIntoNativeArray causes InvalidOperationException on NativeArray. Replacing “ref” by “in” will be improve API and also preserves code level, and assembly level backwards compatibility. It has to do a lot of work (>> 5s). This method copies a rectangular area of pixel colors from the currently active render target on the GPU (for example the screen, a RenderTexture, or a GraphicsTexture) and writes them to a texture on the CPU at position (destX, destY). Using this code to take a “screenshot” of what a certain camera is rendering, the resulting screenshot is upside down in webgpu build, while its normal in PC. renderingThreadingMode to query the rendering threading mode. The Color array is then used to populate a Texture2D, and the Texture2D is written to disk. This plugin aim to provide this feature for OpenGL platform. Although we cannot accept all submissions, we do read each suggested change from our users and 使用 AsyncGPUReadback. The assumption being Texture2D can be easily accessed from C#, but a RenderTexture has to be copied into a Texture2D via ReadPixels() before it can Version: Unity 6 Preview (6000. I’m trying to findout what is going wrong with my code. You could then copy this data to separate AsyncGPUReadback. The many methods I Unity - Scripting API: Rendering. I’m trying to cache the output of a shader as a PNG on disk so I can use it in the future as a straight-up texture and not require the shader to run. Y5 prime spec: Android 8.

Perform all your RequestIntoNativeArrays that you want (I do all mine at the end of the frame) 2. Here is a script I wrote to make it happen. As mentioned by the documentation, using ARCameraManager. Rendering. But at beta times like these I often end up messing with the bleeding edge and I dont expect Unity to be able to offer bleeding edge experimental stuff to me and at the same time somehow insure me against all the I’m calling AsyncGPUReadback. So the majority of time would be wasted waiting for the next Editor update. (OnPostRender with the script being on the same GameObject as the Camera. The idea is to take a screenshot, then get the mouseposition, put in a texture the pixel under the mouse, and use the Request method to AsyncGPUReadback. async readback for OpenGL is now available in Unity 2021.

Thank you for helping us improve the quality of Unity Documentation. 7MB for some reason, and ever 3 blue spikes I get a gigantor green spike where I guess the GC is flushing the toilets. What are my options to work around this issue? Is there a synchronous request for the render texture?

It seems that those renders cannot be all finished within one frame, and thus those finished in next frame will I've been struggling with this problem as well, but I've managed to seemingly fix it. 3. 2. This Unity sample project shows how to use the asynchronous GPU readback API to capture render outputs without blocking the main thread. I am developing for the Oculus Quest which works on OpenGL which means that I cannot use AsyncGPUReadback because it is not AsyncGPUReadback class in UnityEngine. ZAUBAR: Oh shoot. Request works normally, but then you have to do an extra array copy, so while it works it would be nice to get On Unity 2018. It won’t make it faster but it will make it This method copies a rectangular area of pixel colors from the currently active render target on the GPU, for example the screen or a RenderTexture, and writes them to a texture on the CPU at position (destX, desty). The thing i want to do is set texture to ComputeShader, save all pixels to array of struct: struct MapDataStruct { int x; int y; float a; }; and here is whole Hello, Here is how it goes : I use ComputeShader. I have these questions: Does AsyncGPUReadback. I want to get this concept working in the test environment so that I can build jobs into a bigger project I have Unity Discussions AsyncGPUReadback. Although we cannot accept all submissions, we do read each suggested change from our users and will make Unity DOTS - Stress test 4000 sheep with real time navigation - 60 FPS upvotes · comments r/Unity3D r/Unity3D A subreddit for News, Help, Resources, and Conversation regarding Unity, The Game Engine Hi, I’m looking into implementing some TerrainAPI features but at the moment we are still using SetHeights for terrain modification, especially for sticking terrain heightmap to meshes.

I’ve tried most obvious things I can think of, but still struggling to diagnose the issue. I found the Lens Flare and Flare Layer Hey Brendan, I have a question about AsyncGPUReadback I noticed a difference in WebGPU build and PC build, where the data received is in the reverse order in web from the pc version. 3 LTS (all versions), Quest 2, Vulkan (tested with/without URP) Made an empty project, added a new camera with a RenderTexture, and tried to save it to disk. 16f1 2022. Any ideas/suggestions to try would be very welcome, or if any Unity employee could explain a little more about AsyncGPUReadback (known issue, limitation?) so I could know what to try next. AsyncGPUReadback class in UnityEngine. If you're on an older version, you may need to upgrade, or use the workaround in the first thread I linked. 3 beta6 to try using Graphics. Texture. (DirectX is stopping my Compute-Shader due to timeout of the UI does not update. Language English.
