Make sure that everything is really the same. The windows drivers will
most definitely use more AGP memory than the free Linux drivers do by
default, and Windows apps can switch depth at runtime whereas X apps
can't.

All that said though, the Windows drivers obviously receive a lot more
engineering effort from people with better access to information about
the hardware, so some difference is always to be expected.
