Direct3D is a graphics application programming interface (API) for Windows Microsoft Windows. It is part of Wikipedia icon DirectX.

GoldSrc GoldSrc engines ships with a software renderer, OpenGL and initially, Wikipedia icon Direct3D 7, prior to it being removed in 2013 after SteamPipe update. Unlike OpenGL (since detail textures support was added in 2004 with the release of CS:CZ) and like the Software renderer, it doesn't seems to have issues with overbright lighting. Also in James Bond 007: Nightfire James Bond 007: Nightfire, this game used Direct3D 8 instead.

Source Source mainly used Direct3D 9 (Shader Model 2) renderer, which later was upgraded to support Shader Model 3.0 (in all games since Source 2006), but offers backward compatibility with older GPUs using DirectX feature levels. Some third-party engine branch like Tf-16px.png Titanfall engine branch and Strata Source Strata Source use Direct3D 11 instead. Throughout 2020-2022, nearly all of Valve games also added support for Vulkan renderer on Windows, using DXVK to translates D3D9 to Vulkan. Enabling Vulkan translation will require the "-vulkan" launch option (except in Portal with RTX and upcoming Half-Life 2 RTX).

Source 2 Source 2 mainly uses Direct3D 11, but also has options to use the Vulkan renderer.
