Try increasing your overclock to 4Ghz, if it increases gpu usage than yes you are bottlenecking on the cpu.

There could be other causes though, like driver issues, but if increasing the cpu clock rate increases the gpu usage than its cpu related.


Another way to test would be to lower your gpu clocks, if it results in higher gpu usage than the cpu is bottlenecking.

I know its crazy to think with all that cpu usage you're bottlenecking, but its just a fact of Phenom IIs, in less threaded games its even worse.

Ball is right, it could be bottlenecking however AMD drivers for BFBC2 have been crappy at best and have caused all sorts of problem, it widely known that game has been a big problem

Try it though, OC the chip a little to see if you get better FPS

Had that exact same problem on my phenom x 6. Moved to a 2500k i5 and problem fixed.

EDIT: its funny how moving to less cores fixed my problem. Just goes to show AMD sux at processors at the moment.

Balla is right it could be a driver issue,
I don't play BFBC2 but I get no bottleneck on Crysis @ 1080p or any of the other games I play.
I have an X4 at 3.8 on DDR2 and CF 6870s, ATM I'm running 11.4 preview drivers from this thread.
Hope that helps.

Crysis II?

I have a hard time believing your 955 isn't bottlenecking Crysis 1.

its more likely to be CPU but if you don't see any FPS gains at all when you increase your CPU clocks then..you hit the upgrade button..balla jumped over SB just to get rid if that problem..many users did too upon seeing that it has been a cause of under performing..

Get your HT link up to 2400MHz, it helps with dual card configuration's

I don't think he is going to be able to get much more back, hes dipping down to almost 55% usage on both cards.

I saw my 1090T bottleneck my single GTX 470 @ 915 core at times in that game. And its probably one of the "best case" scenarios for AMD x6 chips since it uses a lot of cores.

It just the limitation of the architecture, and sadly its not something you can overclock yourself out of.
