I'll be willing to bet your friend actually has more driver related problems that bugs. If you are using hardware represented on the HCL, there should be very few problems from what I've seen. As far as lagging goes XP pushes the hardware envelope a little further than it's predecessors. You need to have a minimum of 128MB, 256 is much better and a nice fast processor doesn't hurt either.
