since it run fast but i got errors on nivda card but this error is on intel gfx card and also the game turns black after the jungle stage and the games dosent start no more :yucky:
From what I heard, Chankast depend on more CPU power than the graphic card. Any ATI Radeon 9600, 9700, 9800 would probably be enough. You could always wait for the next Chankast release and hope that the Nvidia problem is fix.
