Has any one tried the old, but still cool game Unreal 2 or 1 on the new Alu, iMac? I use Windows XP with Bootcamp, and the games are just choppy but at the same time very speeding! Do I have to wait for new (bootcamp) drivers for the ATI 2600XT? or has any one else already have a solution? or.. is it something else? please help me! thanks in advance oh, and the game I use is the Unreal Anthology pack.
