The New GTA: San Andreas "Sunrise Mod" actually replaces the Sun found in the original game with a new and brighter sun, which changes and improves the lighting quality of the game.
Visual clarity and resolutions have increased as much as %400. The Sun has never looked better in the skies of San Andreas!
The new mod is part of the Space Edison 4.1 Mod for GTA: San Andreas. This mod is available for both PC and Xbox.
