It seems GTA SA can’t handle a high resolution textures. When I modified GTA SA with a dozen high resolution textures for vehicles…boom! The environment textures is missing. Yeah that’s right GTA SA is not supported by high resolution texture, original GTA SA just low poly textures games, evenradeon 9200 can handle it very good. The problems comes when you modify this game especially when replace texture with high quality from the modders. GTA SA is not just driving games, it’s more complicated than you think.
Are you play this game? If not try it guys! You’ll have a lot of fun. Gta San Andreas (GTA SA) is an awesome action driving game.
