I've just bought a new pc with an Athlon 200 XP, 512 ddr, 100 gb hard drive and a Geforce 4 Ti 4600. My old one was a p3 450 with a geforce 2 gts. I'm still getting bad frame rates on some games ' Aliens v predator 2, Medal of honor etc. Does anyone know how to spead them up? Also does anyone know how 2 turn on v sync in medal of honor and tony hawks 3?
