MARSEO  Well, they have done some excellent work with this game performance for us Mac users;

I am running a 6 year old Digital Audio G4 with 1.5GB of cas2-2-2-6 ram, Sonnet Duet dual 1.8ghz and a BFG 7800GS AGP at 425/1250.. And the full game runs as smoothly at maxxed 1920x1200 as my 2.3ghz Athlon 7800GTX powered PC ran the Demo two years ago.

The patch has not done anything as it seems to have dealt mostly with multiplayer exploits. Just wanted to let Powermac people know to not be afraid of this game due to its previous reputation for horrible performance on the PC. Only reason to avoid it would be if you're already burned out by games like the previous Call of Duty or Medal of Honor.

I don't really blame them for stating a G5 processor as a requirement as most G4 systems are soo feeble that its not worth trying. ....But saying that, if you have a G5 (or heavily upgraded dual G4) with a nvidia 6800GT or better you should have a decent experience with this game.
