Thuban bottleneck?

post #1 of 3
Thread Starter 
I have two 5870's in crossfire but playing any CPU intensive game gives me sub 50% GPU Usage. I have seen them as low as 19% on each card during some games of MWLL.

Does this look like a bottleneck to you?

I see Core 6 (CPU-5) taking a pounding constantly.

1980x1080 no AA - gets about 30-50 FPS



1980x1080 16xAA - no real change in FPS



6048x1080 no AA - around 20FPS with frequent lock ups under zooming



Any other ideas where I am getting the drop in GPU usage, I have seen pics of guys running the same map as me and getting 99% usage out of a 5970, when paired with an i7. V-sync is off in all cases.
