Check Display control panel and the acceleration slider.

Control Panels : Display : Settings : Advanced : Troubleshooting

Check Device Manager, and see whether the chipset's interface to
video is running in the fastest mode possible. (On an AGP
system, this is AGP versus PCI, where PCI is slower. There
will be a "bridge" in Device Manager, that mentions AGP, if
it is set up properly.)

You can go to Start:Run and type in "dxdiag" and run the
DirectX diagnostic. Under "Display" there are some test
buttons. There are also some enable and disable buttons,
but you have to be a little careful with the interpretation
of them. On some older OSes, the buttons didn't seem to be
indicating correctly. So I always treat what they're saying,
with some suspicion.

I can think of three levels of communications, for moving
data around. For example, move a texture via AGP protocol
(2166MB/sec perhaps). Move a texture via PCI protocol
(a lower rate, but still pretty fast, maybe 266MB/sec?).
Those would involve mechanisms similar to DMA perhaps,
where Direct Memory Access is handled by a hardware engine
and can happen without processor interaction for each byte.

The third way to do things, is with the processor, transferring
words of data at a time, into the frame buffer. This can
occur at much lower rates, perhaps below 100MB/sec. Depending
on how many software routines are exited and entered, in the
processing of each line of a bitmap, the transfer can be
pretty slow. And that might show up as a slow painting or
removal of an image, from the screen.

The trick then, is determining whether the rendering path
has slipped into such a backup mode, and why.

Better still, disable the whole let and see how things run. One other
thing I would check for are virii or spyware.
