does anyone here have any troubles running GTA4 with a Sapphire 4870 512MB graphics card. when i fire it up it seems a little chunky. in the game i run the benchmark tool and use the recomended settings with no luck. when playing it seems a bit out of sync and the shadows are a bit patchy....
does anyone here have the same problem? ive got the latest driver (8.12) installed. and have updated via the windows live updates.
