This game runs great on my old Mid-2011 imac, using a WINE wrapper to emulate a PC environment. I initially had a problem with the shadows; despite the shadow option chosen I couldnt get them to come on until I added "r_ShadowTexFormat 3" once the game was running! After that the shadows were on and I couldnt detect any lag in the game from it. I highly recommend this game (at least the first half, where you get to fight the evil NORTH KOREANS way off in the future in 2020).
