Quick Specs

Core 2 Duo E8500 3.16Ghz
6G DDR2
Radeon 6790
Win7 64

I have gone back and forth with a ton of drivers using driver sweeper to fully remove between each one. Here's the results. I have turned AA off to rule it out.

11.8 -> game runs, 15-20fps with bad texture pop-in.
11.9 -> Intro movie plays, as soon as it starts to display "project eden" you can tell there is a problem. It's like playing without a video card. maybe moves 1 frame every 15-20 seconds. Both CPU cores spiked at 100%
11.9 Rage Fix drivers from 10/04/11 -> Exact same problem as 11.9.

If I try to force triple buffering in CCC the game crashes on startup regardless of driver.

Just posting this in case it helps narrow anything down. I should note that in other games i've tried 11.9 and 11.9 rage fix drivers do no show any ill effects. My last remaining step is to format and re-install, but i'd rather not.

This is exactly what I'm running into. I may have to try running the 11.8 driver and see if that resolves.

With those drivers, my game crashes EVERY SINGLE TIME after exiting the mutant tv portion of the game. And the final boss is flickering so badly I feel like I am going to have a seizure. Please stop linking drivers that don't work properly, and please only respond when you have new information for those people who wasted 60 dollars on their game currently by not being able to play it. Where is the support? Why is it that us shmoes have to do all of the grunt work to fix this game?
