Im wondering this too. Changed everything possible in config to get better fps, overclocked graphics card, tweaked nvidia drivers, using gamebooster, etc, etc... Im running at around 10-40 fps (depends on map. i get around 10-15 in scrapyard and around 30-40 in skidrow, favela, etc..)
My specs:
AMD 64 2.21ghz
Nvidia GeForce 7800 GS 256mb
can't remember rest
I know they're crappy but read below :S
Usually when i play hacked servers i get around 60-80 fps, how is this possible? Do you need to unlock console for this? And can this be used in public matches ?
EDIT: im running on lowest graphics, 640x400 resolution, windows adjusted for performance, no backround programs running while playing
