Hello, I am having FPS issues that I have never seen before. I'll give examples with two games. I can't get any higher than 11 FPS in Trine no matter what I do. And with Portal, the FPS goes all over the place. It'll go from 100 to 10 in a fraction of a second. The FPS display goes absolutely nuts. Can anyone help me with this? These are my specs, which I know is above the recommended specs.
OS: Mac OS X 10.7.3
Processor: 2.8Ghz Intel Core 2 Duo
Memory: 4GB 1067MHz DDR3
Graphics: NVIDIA GeForce 9600M GT 512MB
