    Hi Guys,

    I'm wondering if anyone can explain the difference I see in my OpenGL speeds when running Windows 7 verses Lion? Or the benifit I may get by using one verses the other to render video. I just upgraded my processor from a 2.8 quad to a 3.46 ghz hex core xeon and noticed a huge difference in performance numbers while testing.

    Same system yields 41.48 FPS in Lion and 70.39 in Windows 7!

    Yes. Apple sucks for OpenGL. Or Apple sucks for OpenGL Cinebench testing. I get same results with W3680 and ATI 5870. 70 in Win7 and 35 in OS X in 10.6.8. Which is also odd as it is a faster card than your 5770 and you only have 133MHz more on CPU clock. Hmmm.

    As discussed in many threads recently, Cinebench is a terrible benchmark. It is completely CPU limited. And, on top of that, R11.5 is positively ancient compared to the current Cinema 4D version of R13.

    If you want a real GPU benchmark, try Unigine Heaven.

    I have posted many times about this.

    Any and all Nvidia cards I have tested score within 3 fps of each other.

    So an 8800GT and a GTX580 are comparable, at least according to Cinebench

    Not sure about benchmarking. (kinda sucks anyways) but I know that D3 runs a hell of a lot better on win7 than it does on my SL build. To be honest, I don't mind either osx now or win7 at least it's not vista.

    excuse me because it's probably not the right place to ask this question, but Unigine Heaven doesn't want to work on my mac. I probably missed something, but I don't know why.

    There's your problem. You realize that there have been driver improvements in Lion and now Mountain Lion, right? Perhaps things that make Diablo 3 run better? Boggles the mind that people complain about low performance, but are running drivers from 2 years ago.

    Because when you upgrade things always run faster on older hardware?:rolleyes:
    I run Win drivers from 6 months ago as they are faster than any of the new ones as AMD is EOLing the 58xx series improvements and only looking at 68xx and above. 58xx series is ever so slowly going backwards due to improvements. It all depends. But the discrepancy between OS X games and Windows has a whole bunch more going on than Apple could possibly make up for in their drivers. OS X has shown to be an abysmal gaming platform. Mostly attributed to crap developers and a puny market share that get's no love. DirectX just eats OpenGL's lunch. Even though technically OpenGL should be quite awesome.
