helpe!

peeeeeeeeeeertty much, my setup is

amd 64 3200, 1 gig kingston, leadtek 6800, 80gig sata

problem is, lately, cant hold steady frames (ie 125). never used to be a problem at all really, now its dipping down to 80 or 90 (r_mode 4, picmip 3 etc). just reformatted, clean install with ET only running, using enditall and its still dropping :<

any idea? it's pretty cold over here atm so it shouldnt be overheating or anything. anyone have a config especially for nvidia which is good at holding frames (or something :S). should i overclock? last drivers btw.

thanks
