This indicates the GPU is the bottleneck, but I'm not sure why it would
be that slow... though one thing I notice now is that the card only has
a 64 bit wide memory bus, that could be the bottleneck. What kind of
numbers does
x11perf -copywinwin500 -aa10text -repeat 1
give? (Preferably without a compositing manager running)
