    A last word guy huh...that's fine when you have something worthwhile to say...but otherwise pretty useless.

     

    This thread was about a software issue not a hardware one.  You were the one who started to spew out supposed bugs in the 2008 Mac Pro that somehow would be behind the slow graphics after wake introduced with Lion.

     

    Seriously...you can now count my Mac Pro from 2008 as one that runs flawlessly under OS X 10.8.3 and 10.6.8.

    I have been benching in games, not LuxMark 2.0.  I prefer real world to any and all of these benchmark apps.  I am using a UB version of Quake 3 1.3.2 with hires texture pack and the timedemo 1 test.  I personally think that this game is the best benchmarking app ever made.  It is what allowed me to find this bug in the first place and has consistently helped me to keep on top of any performance issues.  My fps rates before and after sleep are maintained, prior to 10.8.3, fps rates would drop by 2/3rds.

    I've also tested in Quake3 via the 5870 and it appears to be fixed on my end. I too dislike benchmark apps since they dont really seem to offer real world performance. Too many people spout off what their numbers are without actually confirming their tests numbers/configurations.

     

    I ran LuxMark 2.0 in the following settings:

     

    Scene: Room (Complex Benchmark)

    Mode: OpenCL - GPUs ONLY (CPU IS NOT RELEVANT TO THE BUG!)

     

    The numbers are the same on a FRESH boot and after sleep - only app open was Messages and Luxmark 2.0

     

    I got 284-289 (4 Passes) 2 from Sleep and 2 from fresh boot as my result.
