Hi,
Posted this last week in the Arma 2 (low) performance thread:
-------
FPS is steady at 24-29 (chernarus) but system is far away from utilizing all resources. CPU usage stands at 40-55%, none of the cores rarely exceed 75% usage. GPU usage is at 40-60% on average.
Visibility at 2000. With 10km visibility framerate goes to 15, at 500m to 35. Little gain there. Settings at fairly high but lowering to ugliest possible, resolutions and all, fps is not affected. As if I was CPU limited and I would be happy accept that if CPU usage was even close to full on even one core!
I used playclaw to record gpu/cpu usage and task manager to analyze each core. Arma 2 runs on each core but like I said above, none of the cores is working at full.
What could be the problem? Help highly appreciated.

In case anyone has any tips/resolution I'd be very happy. It kinda sucks running the game at 50% of my system's potential.
I've tried updating drivers, cpucount=4, exthreads=7 etc. to no avail. I've seen a some discussion on problems like this and it is definitely related to quad cores and most also seem to be running x64 Vista or Win 7. What's your OS Jocko-Flocko?
