I've recently purchased the current 2.2ghz MBP and previously I've been playing Call of Duty 2 through XP via Boot Camp. My FPS fluxed from 50-90fps using these specs: Resolution: 1440x900 Rendering: Direct x7 Texture Quality: Extra/High Aniso Filtering Minimal Shadowing However, when running CoD2 on Tiger, I experience terrible performance on the most modest settings. My FPS is now between 30-40 fps and it feels incredibly choppy. My specs for the OS X are: Resolution: 1440x900 Rendering: Normal Texture Quality: High Texture: Trillinear I've tried to change the hunkmegs and perform other console tricks however it doesn't help. I was wondering if others have experienced this problem and if there's a way to fix it. I'd like to play CoD2 on the mac to save myself a reboot. My only assumption is that the software of CoD2 is simply lagging due to being a Universal program written for PowerPC. Any help or suggestions are welcome. Thanks.
