Answer 1

Win32_videocontroller is your best course to get the amount of gfx memory. That's how its done in Doom3 source.

You say "..availability of video controller is offline. I have checked it on vista." Under what circumstances would the video controller be offline?

Incidentally, you can find the Doom3 source here. The function you're looking for is called Sys_GetVideoRam and it's in a file called win_shared.cpp, although if you do a solution wide search it'll turn it up for you.
