In this article, we’ll identify some of the possible causes that could cause directx thread safety to kick in, and then I’ll suggest a few ways to try and fix the issue. 10direct3d is fully thread safe and available to shut down an application with D3D10_CREATE_DEVICE_SINGLE_THREADED.
Multithreading is designed to improve performance by working on one or more threads at the same time.
What is DirectX?
Microsoft DirectX is likely to be a set of Application Programming Interfaces (APIs) for handling multimedia tasks, especially video capture and game programming on Microsoft platforms. Direct3D is also used by other software concepts for visualization and graphics tasks such as CAD/CAM design.
In the past, we often tried to do this by creating one main binding for rendering and one or more additional threads for preparatory work such as loading, creating an object, processing, etc. However, with the built-in synchronization in Direct3D 11, the purpose of multithreading is is to apply each cycle and the GPU CPU before one CPU has to wait for another CPU (especially not letting the GPU wait, as this directly affects timing). In this way, you can create the most jobs while having the best chance of retaining staff. The concept of a single shape for rendering is mostlyMore needed, not because the API is based on synchronization.
What does multithread rendering do?
Multi-threaded rendering is just one setting that you can turn on or off in Fortnite. Multi-threaded products distribute the redrawing work to multiple threads and can improve the performance of multi-core processors. multithreading However, display can cause stuttering and lower FPS on weaker processors.
Multithreading requires some form of synchronization. For example, if multiple threads running in an application need to access the same real device context (ID3D11DeviceContext), this function should use a single synchronization mechanism such as critical sections to synchronize direct access to the device. context. This is simply because the processing of common rendering codes (usually done on the GPU and CPU) the additional generation of common rendering commands (usually developed on the CPU through object detection, loading, data state mutating, resource handling) often use the same hardware (textures, shaders, pipeline state, etc.). Organizing work with multiple messages requires synchronization so that a prudent thread cannot edit or read data that, in the opinion of experts, will be changed in the next thread.
While using the platform (ID3D11DeviceContext) device is not thread-safe, using hardware Direct3D 11 (id3d11device) is thread safe. Because each ID3D11DeviceContext is definitely single-threaded, a single thread can easily call an ID3D11DeviceContext in a minute. When multiple threads need to access the same corresponding ID3D11DeviceContext, they must use some kind of synchronization mechanism, such as cell-critical ID3D11DeviceContext access synchronization, because. However, using critical sections or even synchronization primitives to access a single ID3D11 device does not require multiple threads. Therefore, if an application uses an ID3D11Device to create object resources, the application may not need to synchronize to create multiple object resources at the same time.
Is GDI thread safe?
To improve performance, the graphics toys service with a paletted device interface (such as (gdi), device contexts, scopes, etc.) is no longer supported. This poses a potential hazard to processes that have multiple write threads.These objects are theirs. This danger is easily circumvented by not expressing GDI objects at all.
The multithreading capabilities depend on driver support. Driver How To: Check Assistance provides more selective information about driver query and average results.
Direct3D 11 recently added support for multi-pointers from scratch.accuracy. Direct3D 10 has limited support for multithreading, which is currently multithreaded . This page lists persistent differences in behavior between versions of DirectX: Differences in multithreading between versions of Direct3D.
Multithreading And DXGI
One thread at absolute time must use the immediate situation. However, your application must also consider single-threaded Microsoft DirectX Graphics Infrastructure (DXGI) operations, especially when the application calls the IDXGISwapChain::Present.
For more information about using DXGI threads with threads, see Threading Considerations.
It is not correct to use a context as a principal along with most DXGI interface features. I’d say for DirectX SDK March 2009 and later, the only non-hazardous Qui dxgi functions are Release addref, QueryInterface and there is .< /p>
I’m using the Microsoft DX11VideoRenderer example to renderReal-time Internet browsing in Windows 10 zu. When I run just one stream, the video formats look great. However, when I view more than 4 or 5 paths, sometimes some videos are not displayed in the corresponding windows. The effect may span a small portion of one or all of these video windows.
Also, I get news about intermittent errors in my log file for the following reason:
hr pVideoContext->VideoProcessorBlt(m_pVideoProcessor, means pOutputView, 0, 1, &StreamData );
Error returned: E_INVALIDARG Or one or more arguments may be invalid 0x80070057
I only use the Presenter.cpp and display.cpp DX11VideoRenderer modules in my code. The tank is located at:An example of localized video rendering in DirectX
My initial suspicions at this point can be described as potentially dxvideorenderer being safe to communicate with. I found this information about multithreading: An Introduction to Multithreading in Direct3D 11 which says:
While using the device framework (ID3D11DeviceContext) is not thread-safe, using Phone Direct3D 11 (ID3D11Device) is thread safe.
But since I’m using separate instances to represent the class for each van window, there shouldn’t be any requirement that the ID3D11DeviceContext.not be thread-safe, since each window should definitely have its own ID3D11DeviceContext instance.
Does anyone have any ideas or experience with this sample DX11VideoRenderer software and what exactly might be causing this problem?
I need to duplicate the annoyance in the same window so it doesn’t look like a functional multithreading issue anymore. If I manually resize the window multiple times, sometimes I should be able to flash in the video home window. When this happens, I see in my log that the same
