Thanks for the kind words. It took me days to figure this out, due to the randomness of runs. At one point I thought it was Tessellation, at another I thought it was ATITraytools interacting with the program, at one point I thought it was ProcessAffinity settings. All false leads

When I finally by the weekend, when I starting looking at the CPU/GPU interactions during stutters - I finally got it. It took all those plots and graphs to prove it however.

Yes Phazon, that's exactly how it seems to me - the CPU gets starved for info and stops - then the GPU follows. In many runs you'll see the CPU start to come down in load - but it picks back up before the GPU is effected.

I wanted to put this out here to stop folks from running out and buying video cards right now. By all means, wait until it all stabilizes then see what you need.

Last thing: As you can see in the first series of graphs, my HD5870 is running at max clocks just fine. One of the interesting things that's occuring apparantely is the HD6000 series cards are not "clocking up". So HD5000's are operating one way - while HD6000's are operating in another.

S!

Gunny
