Tool to display video memory usage?

[Flo]

I'm curious if this is even possible. I'd like to know how much video memory a given game is actually using.

Or if it's not possible to read video memory usage, is it at least possible to find out if the card is using system memory via AGP?

I'm using a Radeon 9500 Pro.

Yeah for some odd reason you just cant find this out, if anyone knows the reason do tell.
