The ATI may be part of the problem - I haven't seen any appreciable slowdowns myself, but I have a TNT-based chipset and glx running here (which means little resource wastage), and at home I have a GeForce4 w/ 128MB on the card (where nvidia and Linux have always played nicely together.) I'll play with it a bit at home and see what I can come up with (I'll be re-building my comp at home completely, either this weekend or early next week) /P
