Hi everyone, I have GTA San Andreas for the PC. I have recently upgraded my operating system from Windows Vista 32-Bit to Windows 7 64-Bit, and now when I play San Andreas all of the colours on the 3D models are fuzzy and wavy, as if petrol has been splashed over them, instead of being plain and shiny. If anyone could help me resolve this issue and return the game to its former glory, I would appreciate it a lot. Thanks.
