I purchased Counter-Strike Source and started to play it with every graphics tweak as high as possible. i have a pentium 4 2.4 ghz, radion 9700 pro, and 1gb of system memory. I was getting lower fps than my friend who has a pentium 4 2.6 ghz a geforce 440 128mb and 128 mb of system memory. I lowered my settings to see if that was the problem but i still, with everything as low as possible, get around 30 fps while my friend gets over 90 fps at all times. This is distressing me because i am unable to play well due to frame lag when in combat and i do not understand why i cannot get my frames to go any higher even with lowered graphical quality settings. How can i get my frames to go up and why is this happening with me and not my friend.
