If nothing else, I'm just curious as to whether the FPS I'm getting with shaders is normal for my computer.

Basically a fresh install of Vista 64

4 GB 800DDR RAM
Intel Core 2 e6850
nVidia 8800 GTS

And yeah, just trying to guage what my machine should be running it at with shaders on at 640x480.

I get usually 30-45 FPS.

Also it's running in a window.
