I get ridiculously low FPS in older HL1 games and its really making me mad.
Sometimes I can restart my computer and it will work with the normal 100 fps..
Reinstalling drivers works once but after I play the game for a while and exit then open it back up again it goes back to 10-20 fps and major lag.
I have a ATI Radeon 2600 XT 512 MB
Any Help?
