I rather stupidly installed the Q318966 Update to the GDI for WinXP by Microsoft and after about 5 minutes of play I get this THICK foggy effect in GTA3. I've uninstalled this using the add/remove programs but it didn't change a thing. Also installed the catalyst 2.1 drivers and that made the game a little choppy. So does any body know what files the Q318966 update replaces, So i can get them from a different Install of windows.
