I have a MacBook Pro (CD 2,16 / 1GB / 256MB) and i am playing Counter-Strike: Source in my LAN. I use Bootcamp & Windows XP SP2. I even play with 1280*768 and all settings to low/off. And the performance suxx. There are usually up to 26 players on the server. But even if I am one-on-one with the enemy and we shoot each other - FPS becomes red lows down to less than 30 frames. Guys with worse hardware have no troubles. Or can't Mac for 2k$ handle a 2 year old game normally even on low settings? It SUXX!
