Is there a way to get how much of the graphics cards real memory one uses? And in the case it does, what that memory is used for? ( textures, geometry, framebuffers etc.)
I've tried OpenGL Profiler and Driver Monitor on Mac OS X to get this kind of info but I can't find similar tools on Windows or Linux.
I tried gDEBugger(2 beta) and it seems like an ok tool on most accounts but I couldn't find any info on the memory usage of my app.
