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 .
DirectX Diagnostic Tool displays information about the current display settings and the video hardware on the Display tab. If the computer has more than one monitor, then DirectX Diagnostic Tool will display a separate tab for each monitor. This tab can disable DirectDraw, Direct3D, and/or AGP Texture Acceleration for
This can reduce the input lag associated with v-sync. This is limited to DirectX 9, 10, and 12. [12] AMD Link allows users to stream content to mobile devices, compatible Smart TVs, [b] and other PCs with Radeon video cards, enabling them to use their PC and game on them remotely. It can be used both locally as well as over the internet.
With the introduction of DXR in October, four new features were added to DirectX 12: [1] Acceleration structure is a representation of the 3D environment that is efficiently formatted for the GPU. This environment is the plane that is used to create the starting points. The structure allows for modifications to be made and has optimized ray ...
UNIGINE 1 had support for large virtual scenarios and specific hardware required by professional simulators and enterprise VR systems, often called serious games.. Support for large virtual worlds was implemented via double precision of coordinates (64-bit per axis), [12] zone-based background data streaming, [13] and optional operations in geographic coordinate system (latitude, longitude ...
The performance discrepancies may be due to poor Nvidia driver optimizations for DirectX 12, or even hardware limitations of the card which was optimized for DirectX 11 serial execution; however, the exact cause remains unclear. [63] The performance improvements of DirectX 12 on the Xbox are not as substantial as on the PC. [64]
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 ...
If more than one driver is used, Windows will disable one of them. [12] WDDM 1.1 does not have this limitation. [13] WDDM 1.0/1.1 does not allow some modes that were previously handled by the driver such as spanning mode (stretching the desktop across two monitors) [14] [15] although Dual View is still available.
