I've noticed before i upgraded my gpu and after that the cut scenes/loading scenes jutter, the sound crackles and goes out of sync. It wasn't always like this when i first got it, i had a 1gb Radeon HD 5770 then and at xmas i just put in a 2gb XFX Radeon HD 7870.

My spec is as follows

Q6600 G0 @ 3.44ghz
Asus P5k Premium WiFi
4gb XMS2 Dominator PC2-8500
XFX Radeon HD 7870 2gb
Win7 x64

I had that problem as well when I played on a laptop. It's prolly due to bad hardware.

Surely if it were bad hardware everything would be effected. Its just Crysis 2 that the sound jumps out of sync. Im playing Far Cry 3 and that runs great.

well nams is correct as well as that mobo suks and is old.
