I haven't seen anyone else posting about it but this is a fairly big deal for some of us. So far, Ive had a really excellent experience with Diablo 3, Starcraft 2, and once borderlands 2 installs ill see how that goes. Testing on a quad 2.8 2010 mac pro with a 5870 and 16gb of ram. games running at 1920x1080. Diablo 3, max settings Solid 60fps... the only word i can find to describe it is, buttery. Its amazing now, because previously, it was playable smoothly at mid settings, so if the game got busy it wouldn't hang and get me killed. In my play testing, I'm confident that the game will not stutter at Max settings and get my hardcore character killed. its great. SC2, Max settings, overall 55-60 fps with slight resource hangs occasionally. but those drops in fps (down to 15-20) are so quick and the game recovers fast enough that i couldn't actually feel the hangs while playing. but they did show up when i moused over to see the fps information Borderlands 2 Ill find out tonight. Looks like the New OpenGL support seems to be the ticket to a better Mac OS X gaming experience. Hoping it just gets better.
