Hi, Is it possible to update the os x graphics drivers for the 650M in the retina MBP? Installed Starcraft 2 heart of the swarm yesterday and am getting hideous framerates (10-20). I'm sure the machine is capable of more than this, I was getting 60+ in Wings of Liberty although the fps in that has now dropped too. Tried resetting the SMC in case it was that but no dice. In the latest drivers for windows it says it has important updates for HotS, but can't find any mac drivers anywhere. I'm not keen to bootcamp and run the game on windows as windows looks either terrible (in lower resolution or with increased dpi) or absolutely tiny on the retina screen.
