graphic card memory

[Dampire]

Hello

I have a problem. I need to check in my program (OpenGL with GLUT)
how much memory is available (for textures) on the graphis card.
I tried this with allocating textures until the memory is full, but the
result delivers not only the real graphic-card memory but the sum
of graphis memory and memory mapped from main memory through the AGP bus ("AGP Aperture Size", that can be set in the BIOS)

Does somebody know a way how i can check the real graphic memory only, without the AGP mapped memory?

Thanks for any help, and sorry for my bad english :)

Hi...
There is a program that does it...
glView

It tells you what kind of extensions your graphics card supports and what graphics card you need to support an extension...
