ive had some troubles with my fps ever since I got ET, the fps changes allot and its hard to get over 40, 20 on radar, anyone have any ideas on tweaks or something?
ive got a 1.6 ghz comp with 512 ddr ram and g-force 4 64 mb.
I play with 640x480 and have turned down the graphics pretty much.
Also if you have any tweaking tips for aiming better it would help too, thanks.
