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 ...
In Windows 8.1, WARP has been updated to support feature level 11_1 and tiled resources. [5] In Windows 10, WARP has been updated to support Direct3D 12 at feature level 12_1; under Direct3D 12, WARP also replaces the Reference rasterizer. In Windows 11, WARP was updated to support feature level 12_2 (DirectX 12 Ultimate) with variable rate ...
The first beta of DrawPrimitive shipped in February 1997, [21] and the final version shipped with DirectX 5.0 in August 1997. [22] Besides introducing an easier-to-use immediate mode API, DirectX 5.0 added the SetRenderTarget method that enabled Direct3D devices to write their graphical output to a variety of DirectDraw surfaces.

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]
The Celeron G440 also does not support Hyper-threading. Celeron G460, G465 and G470 support Hyper-threading. HD Graphics (Sandy Bridge) contain 6 EUs like the HD Graphics 2000, but does not support the following technologies: Intel Quick Sync Video, InTru 3D, Clear Video HD, Wireless Display, and it does not support 3D Video.

One of the limitations of WDDM driver model version 1.0 is that it does not support multiple drivers in a multi-adapter, multi-monitor setup. If a multi-monitor system has more than one graphics adapter powering the monitors, both the adaptors must use the same WDDM driver. If more than one driver is used, Windows will disable one of them.
