Amount of video memory

OpenGL
1

Is there a programmatic way to find out how much memory a video card has? And how much is currently used / available?

This has come up quite a bit, and it seems there are 2 ways to get the total video ram. One is to use the IDxDiag* interfaces, and the other is to query WMI (windows management instrumentation).

I’ve slapped together a couple of simple wrapper classes you might find useful:
http://www.spectranaut.net/sourcecode/WMI.cpp
http://www.spectranaut.net/sourcecode/DxDiag.cpp

Very basic but might be a good starting point…

There’s no way to query currently available video ram, just the total on board.

Thanks! That gets me on the right path.
