I'm running stock boot camp on an XP (no additional drivers). I have a standard 2.66 Mac Pro (1gb ram, 7300 gt) My performance in-game is really poor... I've tried running it at various resolutions (1900, 1300, 1200) with high/medium settings. My memory usage is yellow on high textures and full green on medium. Do I need to update my graphics card drivers? Are my stock memory and card causing the problems? I just ordered 2gbs of ram so hopefully that'll answer my question.
