Just got the new machine up and running, and most everything works under 10.7.4. The only issue I have is graphics performance. I've installed the Combo OpenCL Enabler for the Fermi 5xx via Multibeast and downloaded CUDA (Which shouldn't do anything for Graphics anyway). When I run Starcraft or Portal 2 I'm getting framerates in the low 40's and then they drop to the single digits as if I was using integrated graphics. Is there anything else I need to do in order to take full advantage of the card? Or a way I can check if something is amiss in the kexts?
