Yes, I thought about that. Though atm I am more interested about the reported 
agp usage, which behaves differently in linux apps.

Actually, wined3d usually takes only 5% cpu time in nice games, the rest is 
split up on the game and 3d driver(usually 60% driver, 35% game). I think 
that windows uses some marshalling to move the driver to another thread, 
which will help on dual core machines.

I think its time to get a windows license for my other machine :-/
