So far I have tried pretty much everything.

Installed Rage performance fix - Disabled CatalystAI(http://www.gamesas.com/index.php?/topic/1236814-ati-stutter-fix/) - Applied the stuttering fix(http://www.gamesas.com/index.php?/topic/1237017-total-ati-fix/)

Did the same thing with normal 11.9 Drivers. Nothing seems to work. Stuttering is unberabel, and textures keep popping like crazy.

So what I want know is that, has anybody else who has dualcore card from AMD/ATI have gotten Rage to work?

i fixed my stuttering with rage and the fps only problem i have no is the annoying texture popping and artifcats

This fix will probably come when they get the crossfire problem fixed as well, since the 6990 is essentially set up in that way. The latest drivers they released were only optimized for single card setups. I don't believe much work was done on rage to test on any environment that differed in some way from a console, and until consoles have multiple GPU's you'll get these problems from game developers pushing out console ports as fast as humanly possible.

Same here......just did fresh install of 11.9 drivers and disable CatalystAI.....the stuttering stopped, but texture popping is insane.....hopefully AMD fixes this soon or a user fix is found......*sarcasm*Hey I only paid 700€ for 6990 and it's low priority for AMD how nice =)
