the graphics sweeps are out of sync, they seem to be random across a song, some parts in sync others completely out, i've checked the ati drivers are upto date.
I cannot change it to a standard pc as it is a hyperthreading pc and I will loose all the performance.
I ahve played around with dxdiag, not got anywhere.
The thing is this is an upgrade, i've used verson 3108/ 3110 / 3120 and all of the worked perfect on the same setup, i only got the upgrade because I wanted to be up to date, what has changed on the graphics from all the other versions, 3120 was working perfect until I upgraded it tonight
