Latest Doom 3 mod.
"Before the new Doom arrives, why not revisit the last one? This mod makes no gameplay changes to Doom 3 but adds over 600 HD textures, overhauls lighting and sounds, restores cut content, and adds hi-res UI and fonts. It also comes with graphical options like FXAA, FOV, and anisotropic filtering, and includes support for widescreen resolutions up to 4K."
