Long story short I am switching form Macbook Pro to PC Desktop.
I was able to find out that after 20 minutes of running the game on mid graphics with 20-30 fps my computer's temperature rose to above 95C and sometimes goes above 100c. After 20 minutes the fps jumps down to 8-20 fps until it eventually turns off from over heating.
The best I can play is when i place the computer right by my window with a fan also blowing right on it, I can run the game at low graphics with 20-30fps for over an hour or two.
17' macbook pro 2010
OS: Lion 10.7.3
Processor: 2.66 HGz Intel Core i7
Memory: 8GB 1067 MHz DDR3
Graphics: NVIDIA GeForce GT 330M 512 MB
I heard they are fixing the FPS issues for macs on the "release build", we played the "debug build" in open beta. This however won't fix my overheating issue.
I bought a PC desktop on sunday and the game ran at 60fps constantly.
PS. my friends who have 15' MacBooks can run the game on mid graphics with no issues and they are older computers.
