Both DirectX 11 and DirectX 12 supports make multithreading an attractive alternative to address the performance bottleneck of rendering. However, due to the complexity of both the renderer and multithreaded programming, it’s necessary to carefully understand the characteristics ...
Advanced Rendering with DirectX 11 and DirectX 12 (presented by NVIDIA) AGENDA DirectX 12: more control & responsibilities How to efficiently drive DirectX 12 on NVidia GPU New DirectX 12 programming model use case DirectX 12 & 11.3 new hardware feature use cases Q&A DIRECTX 12: MORE CONTROL Gi...
A game developed in DirectX 12 usually has better performance than DX 11, but if the devs aren’t familiar with the API, the result can be a disaster. This is one of the reasons that there are so many unoptimized AAA game titles in 2023. This is why some devs still choose DX11 in ...
To demonstrate the power gains of DirectX 12, Intel locked the framerate of the demo, rendered with DirectX 11 for a period of time and then toggled to DirectX 12 rendering the exact same content for an equal period of time. The graph below clearly indicates that DirectX 12 CPU power cons...
Does anyone know if the problems with the 13900k and the 14900k running direct X12 games and programs have been solved by either Microsoft in Windows 11 or by Intel? Aside from lowering your p cores and all the other tuning possibilities which are not actually fixes. Tradu...
D3D12_MEMORY_POOL_L0 = 1, // 代表 SysRAM D3D12_MEMORY_POOL_L1 = 2 // 代表 VRAM,由于 UMA 架构下 GPU 没有独立显存,而是与 CPU 共享 SysRAM,所以 L1 对 UMA 架构来说没有意义 } ; typedef struct D3D12_HEAP_PROPERTIES { D3D12_HEAP_TYPE Type; ...
This could reduce reliance on off-chip memory bandwidth for performance scaling Because data can flow between small tasks in a fine-grained way, the programming model doesn’t force the application to drain the GPU of work between data processing steps. ...

‘11’” or “Feature Level ‘12’”, these numbers are mostly independent of the API version and are not indicative of game performance. For example, it is entirely possible that a “Feature Level 11” GPU could substantially outperform “Feature Level 12” GPU when running a DirectX 12 ...
Performance Results We focused our performance testing on Intel Gen 11 and Intel Xe hardware, with the support of Intel, as well as NVIDIA Turing hardware. There were similar performance gains on all the supported hardware. Testing Hardware ...
