slightly off topic this..

you know with VAR you can (kindof) request AGP memory.. as this only works on geforce cards, is there any way in windoze to just allocate some agp memory yourself?

If so would this work with OpenGL?

Sorry I'm not sure, but I would definately think that it is not possible to alloc AGP memory with ordinary Windows.
AGP was only meant to be used with the graphics card, so that would be just DX and OpenGL.

Why would you want to do that anyway?
If you wanted it to store geometry in AGP for other graphics, I'm especially thinking of non-TnL cards. Think of it this way, the driver would have to copy the data back to SysMem to have the CPU perform calculations on it. And reading is REALLY slow.
