Very interesting... I'll want to read the entire article when time permits. But it sounds like I'm stuck with micro stuttering as long as I have those 2 HD 6850s in Xfire. Or until AMD finds a software solution and implements it in their drivers.
Yes, Ive been wishing for that for a long time now. I found to reduce microstutter try to cap your max framerate to at least 45fps and have it locked there with Vsync enabled. If the fps start dropping down just lower your graphical settings until the framerate locks at your set max. U might have less graphical eye-candy but you will have much more enjoyable smooth gameplay.
