Ok, wow, where to even begin here? After going back to experiment with the previous drivers, and then going back to the 8.95.5, I am now experiencing the SAME EXACT issues you're experiencing. My FPS remains well above 60, even with uber enabled (vsync off) with GPU usage at 90 -99% in relatively calm areas , but when I go into battle, my GPU usage drops down to the 40%' ish mark and my FPS tanks into the low thirties or even into the teens now. It's like opposite land..... W T F ?!?!?!?
Now, no matter what I do, my performance is crap and nothing like it was prior to me messing with previous drivers.
I don't know what the hell I screwed up but these drivers are really starting to piss me off, as they are seemingly extremely sensitive and unstable.
Well, WiL, look on the bright side, this pretty much confirms your cards are fine and this basically narrows the problem to either driver issues (DAMN YOU AMD) or poor 7900 series optimization by Projecktd, or perhaps even a CPU bottleneck. I am running a 2500k @ 4.5GHz. Something here is VERY wrong, but not with our cards.
EDIT: Can somebody with a beefier CPU, a 3930k or x even, and CFX HD 7970's, test TW2 out?
Thank you so much for trying to trouble shoot and get to the bottom of this, but now I feel bad for messing you up too. But it is clear these drivers need major work since you got shafted by AMD as well. You'd probably need to do a clean install? Looks likely you left some RC11 drivers in your system I guess. I however, did a clean install from RC11 to 12.4 and didn't improve my performance in TW2 so :shrug:
I just wanted to play the game in its beauty so I just live with it dipping into the 50s from time to time. I THOUGHT it was a CPU bottleneck at first. Why? Because on one of the missions I was getting fluctuations of 55-60 during the dragon scene in "At The Fore", with GPU usage in the 45-55% so I decided to set my 2600k from 4.5ghz back down to 3.6ghz. My FPS tanked some more from 55-60 down to 45-50 so I immediately thought it was a CPU bottleneck. But something else is going on with the drivers that are not utilizing the TWO GPUs enough because when I disabled CF, the single 7970 was also getting 45-50FPS or rather, same FPS as CF enabled.
Anyways, thanks ELCID777 for trying to troubleshoot for me and then in turn getting owned by AMD. Much appreciated, I hope you get it figured out, that way you can fix mine too =D
