DDrawCompat is described as 'DLL wrapper aimed at fixing compatibility and performance issues for games based on DirectDraw and Direct3D 1-7. Partially supports GDI as well. There is no API conversion involved, most of the rendering is still done by the native DirectDraw/Direct3D 1-7 and' and is an app. There are more than 10 alternatives to DDrawCompat for a variety of platforms, including Linux, Windows, Wine, Flathub and Mac apps. The best DDrawCompat alternative is Wine, which is both free and Open Source. Other great apps like DDrawCompat are Proton, ProtonPlus, ProtonUp-Qt and Protontricks.
Even if Windows supports DirectX natively, using WineD3D can enhance backwards compatiblity with older games, especially on Windows 8 and newer that don't support 16 bit screen modes. Another possible use is to emulate unsupported versions of DirectX, or porting DirectX...
This project provides DLL wrappers for the DirectX 1-9 graphics components. Its purpose is to disable the use of the Direct3D 9 user-mode display driver provided by GPU vendors. This forces the runtimes to use D3D9On12 instead.
VK9 (Formerly SchaeferGL). Runs Direct3D 9 applications on Windows or Linux (/w Wine) over Vulkan.
