In Direct3D 11, the concept of feature levels has been further expanded to run on most downlevel hardware including Direct3D 9 cards with WDDM drivers.. There are seven feature levels provided by D3D_FEATURE_LEVEL structure; levels 9_1, 9_2 and 9_3 (collectively known as Direct3D 10 Level 9) re-encapsulate various features of popular Direct3D 9 cards conforming to Shader Model 2.0, while ...
Direct3D 9Ex, in conjunction with DirectX 9 class WDDM drivers allows graphics memory to be virtualized and paged out to system memory, allows graphics operations to be interrupted and scheduled and allow DirectX surfaces to be shared across processes. [41] Direct3D 9Ex was previously known as version 1.0 of Windows Graphics Foundation (WGF).
Like the Nvidia GeForce 400 series graphics cards, the Nvidia GeForce 500 series supports Direct3D 12.0 (feature level 11.0), OpenGL 4.6, and OpenCL 1.1. The refreshed Fermi chip includes 512 stream processors , grouped in 16 stream multiprocessors clusters (each with 32 CUDA cores), and is manufactured by TSMC in a 40 nm process.
Linked GPUs will allow DirectX to view graphics cards in SLI or CrossFireX as a single GPU and use the combined resources; whereas Unlinked GPUs will allow GPUs from different vendors to be utilized by DirectX, such as supplementing the dedicated GPU with the integrated GPU on the CPU, or combining AMD and NVIDIA cards. However, elaborate mixed ...
WARP is a full-featured Direct3D 10.1 renderer device with performance on par with current low-end graphics cards, such as Intel GMA 3000, [2] when running on multi-core CPUs. [3] To achieve this level of rendering performance, WARP employs advanced techniques such as just-in-time compilation to x86 machine code and support for advanced vector ...
DirectX Video Acceleration (DXVA) is a Microsoft API specification for the Microsoft Windows and Xbox 360 platforms that allows video decoding to be hardware-accelerated.The pipeline allows certain CPU-intensive operations such as iDCT, motion compensation and deinterlacing to be offloaded to the GPU.
