Not getting full acceleration with GTX 660 Ti

Try manually setting to the Gen 3 option and save as that is the best option for your GPU requirements.

The system booted fine with PEG set to Gen3, but I did not see any improvement.

OS X Configuration, Tuning & Utility Tools (second option down):

I've also got a Nvidia 660 TI and am disappointed with the graphics performance in OSX. Using Luxmark in OSX I get around a 580 score. When I boot into windows and run the same luxmark test, I get about 1100. I'm running Yosemite 10.10.1 using the latest nvidia web drivers (343.01.02). OSX performance has actually been around 580 using the native drivers as well as running previous versions (10.9 & 10.8).

I tried LuxMark and Unreal Heaven before and after setting PEG to Gen3. LuxMark reported a score of 591 before and 595 after. Heaven results were equally similar before and after.

I'm about to try Gen3 with IGPEnabler=Yes just in case.

No change with IGPEnabler set back to Yes. Scored 593 on LuxMark.
