Ok guys i'm getting like 20-30 fps on cs:source. I have a p4 3.0 ghz with 1 gb of ram, 650 watt power supply, and just recently bought a $400.00 ATI X1900 video card with all the newest drivers....this cards clock speed is 650 mh with 512 memory....it's a monster it literally weighs 5 lbs. Whatever is happening doesn't make sense. When i first got the game I was running an ATI x700 card which got me 170-200 fps. So I figured replacing it with an insane card would solve the problem....I an anal with spyware and viruses so there are none on my machine....the computer sits in an air conditioned room...And i realize people are having problems with source in particular but with those specs i shouldnt have any trouble. i just dont know what else to do...any suggestions anyone???
