So as per the sticky:
CPU: i7 920 [stock for testing purposes... just to rule out an unstable OC if anything]
RAM: 12GB 1600MHz DDR3
GPU: GTX580 1.5GB VRAM [Currently on 266.58 drivers for folding reasons, but also tested 275.33 prior to this post, same problem]
OS: Windows 7 x64 Enterprise
Issue:
I get framerate drops from a capped 60 to a ~30 in the Ironclaw Munitions Factory. Why is it a problem? Well my 920 is hovering at about 30% usage on one core and my 580 is hovering at about 40% utilization.
RAM usage also never breaks a 1GB point.. so yeah :\
I'm honestly lost.
