Works with versions 1.0 of the GTA games. It is generally not compatible with the Definitive Edition (Remastered) versions, as those use the Unreal Engine.

Users can tweak the mod by editing the skygfx.ini file. This allows for "mix-and-match" configurations—for example, using PS2-style color correction combined with Xbox-style vehicle reflections and PC-style shadows.

Restores the dynamic stencil shadows for characters and vehicles.

For any player looking to replay GTA III , Vice City , or San Andreas on PC, the extraction of skygfx.7z is highly recommended. It is low-overhead, stable, and arguably necessary to experience the games as they were artistically intended.
