Our PC specifications are intended as rough guideline, and are based on mainstream desktop PCs using these specifications. Very often laptop or budget PC manufacturers may carry the same specifications but won’t have nearly as good performance, so your experience running Rocksmith on a laptop or budget PC may be less than optimal.
yep finding this out my desktop is a hp about 4 years old running xp on fairly good specs and when i tried to run the steam demo it just switches off my monitor telling me no compatible signal(think the demo is hd but my monitir doesnt support it) dont think i fancy buying a new desktop just to play the game ive got for ps3, its a shame as it would have been handy to be able to bugger of to the pc when the other half needs to watch her bloody soaps.
