After reading this thread and experiencing the same "sorry ass FPS" with my monster rig I was disappointed. .,,,,,,then I thought..???? something not right here? The frame rate was horrible at the desktop res? 1920x1080. Come on I thought and almost ripped CMSF from my HD in frustration. But I remembered the increase in frames from one comp to another from before so I scratched my head,...???
Then I booted up the game at the UI res (much lower). Still laggy,....what! I thought? So then I rebooted again at the desktop max and wouldn`t you know it,.....wahla nice and smooth as you would expect.
Seems funny but it worked,.....CMSF goodness as one would expect. Not sure of the frames now but who cares its glassy smooth at full max settings with AA.
Weird Stuff,..hope it helps some.
