Battlefield 3 Bottlenecking

[Frostey]

Hello tom's hardware!

I seem to be having a problem. I currently have a i5 2500k with a Hyper 212 evo heatsink and crossfire Sapphire 6950's 2gb. When I run Battlefield 3, on 1920x1080 ultra graphics with no AA, my CPU usage hits 90%+ while my GPU usage stays around the 50-69% mark. I have overclocked my CPU to 4.4 and still no change. Is this normal or is it still bottlenecking?

Whats your FPS?

I get 85 when I'm not in combat then it can go as low as 25. Average is around 40-55.

Well is it 64 player 48 or 32 because those can change how your system behave

64 and 48 player.

..... a 2500k at stock clock should have no problem running BF3 ultra... especially with two 6950's. There's gotta be some other problem in there somewhere.

Update all your drivers yet?

 

[Frostey]

My drivers are up to date.

Edit: Guess nobody knows why.

chances are its a hdd problem. if its 7200 rpm its likely your not getting the textures fast enough. if you have another identical drive try raid 0.
neither parts are classically bottlenecking as far as gpu and cpu go as neither are hitting 100%.
try using the bf3 configuration and limiting your fps to 60 this should stop the fps droop and smooth out the stutter if there is any.
also try using an fxaa injector. it doesnt just work with nvidia cards and doesnt have a high overhead that comes with fsaa.
switch to hbao rather than ssao it looks better and has a lower overhead.
you should now be able to run aa without impacting the fps to much if you dont bother with the injector.

I'm running BF3 max with a 7200RPM drive, and no fps drops...
