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 ...
The System tab displays the current DirectX version, the computer's hostname, the operating system's version, information on the system BIOS, and other data. The DirectX Files tab displays information about the versions of specific DirectX system files, which are portable executables or dynamic-link libraries (DLLs). DirectX Diagnostic Tool ...

New graphical features are Depth Bounds Testing and Programmable MSAA.
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]
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.

DirectDraw (ddraw.dll) is an API that used to be a part of Microsoft's DirectX API.DirectDraw is used to accelerate rendering of 2D graphics in applications. DirectDraw also allows applications to run fullscreen or embedded in a window such as most other MS Windows applications.
When SDL is compiled, the appropriate modules are selected for the target system. The following back-ends are available: [7] GDI back-end for Microsoft Windows. DirectX back-end; older SDL 1.2 uses DirectX 7 by default, while 2.0 defaults to DirectX 9 and can access up to DirectX 12. Quartz back-end for macOS (dropped in 2.0).
