That is indeed a rather old board. I think it may not
be the board that's slow but the bus between the
cpu and vram - since non-opaque window send a bunch
of data on every repaint from system memory to
vram, the bus speed is very important.
The only suggestion I have is to provide the user with
the ability to turn off the effects. So if it's
really slow (perhaps you can detect it yourself, too -
time the repaints), then turn them off.
Thanks,
Dmitri

On the modern Vista machine the test app works also fine if I disable d3d
support (sun.java2d.d3d=false) even if this causes a higher CPU utilization.
