on a laptop I would bet it's a 5400Rpm.

Have u tryed using the same VSTis as a DXi?.. some stuff works better like that... maybe a bigger buffer can help out a bit! :(

I will go a little down the line and say that most of times u r better off using the DX driver 4 yer soundcard ... unless u plan 2 rewire or somethin' I would just use DX driver...
