You're out of system memory. 8GB isn't enough...get more. That there is your bottleneck. Problem solved.

Let me say this once. Its the CPU holding you back @ 1080p. In the SS you provided you are getting 150 fps. No way in hell the CPU is going to give you more. I had a HD 6990 @ 1Ghz with 2500K @ 4.8Ghz and in some Maps with 64 Players my GPU usage would drop. Yeah GPU was Bottleneck 90% of the time but 10% of the time is the CPU. You have GTX670s which are way faster and only 4.5Ghz so you will CPU the CPU Bottleneck % increase. Nothing you can really do unless you clock it even more. I play @ 1440p with 2 x HD 7970 and get 80-120fps MAX setting and i dont really care if CPU is bottleneck or not. Play the game and have fun.

It's cached, not used. There is a difference...

My 3770K at 4.2GHz gives my two 7970s at 1125/1500 about 55% usage on both.

I have the latest driver 306.97 and also tested the last beta driver 310.33 and the same problem

What? 8GB isn't enough? Seriously? The usage there is showing only 4GB and I have 8GB, so there is 4GB left to be used tongue.gif

But wouldn't it be a bottleneck if my CPU usage were at 100% instead of 40%? I will clock to 4.8Ghz to see if there is difference in the usage, wait a second

The only thing I could think of is the Windows Optimization making it seem like none of the cores are full... But I have no idea about that... Your VRAM isn't maxed is it?

It isn't a CPU bottleneck mate. GPU usage is low purely due to resolution limitation, 1080p is too easy for GPU's these days.

VRAM being used up fully would result in 1FPS. So it's not that...

And thus his CPU can't push the cards a that easy resolution so he's CPU limited... doesn't take a genius rolleyes.gif
