Please suggest the easiest way to determine video card memory from OpenGL application. I mean initial memory installed on 3D card, not texture memory. Thank to all!

The video card specifications has something like, 64MB, 128MB, 256MB. This memory constitutes of the overall (vertices, texCoords, indices, normals, per-vertex attribs, texture memory, framebuffer memory, render-to-texture memory etc...) memory available inside the graphics card. So it is advised to make efficient use of this limited resource.

If your question is how to query how much memory is available on the graphics card from the OpenGL application at runtime, I don't think that is possible.
