Hi, I''m currently trying to figure out a way to test for the amount of video memory present in the video card installed in a users system. Any good suggestions for how to do this? The target platform is Windows 95/98/ME and Windows NT4.0/2000. Essentially, I''d like to automatically set some texture options, and I can easily see this being broken down by category: less than 16 MB 16 MB 32 MB 64 MB or more Any help would be much appreciated - Marc Jensen

If your using DirectX you can use GetCaps() to do it:

DDCAPS ddc;
memset(&ddc,0,sizeof(ddc));
ddc.dwSize = sizeof(ddc);
lpdds->GetCaps(&ddc,NULL);
ddc.dwVidMemTotal // Total memory
ddc.dwVidMemFree // Free memory

I would like to comment that the dwVidMemTotal field, doesn''t return ALL videomemory present. It is all the video memory minus the size of the structs that the driver uses to store stuff.

Does anyone know where I can find the REAL amount of total video memory?

Hmm the "total" is the mem available to DirectX. Maybe try adding the memory required for the current resolution? Like 1280x960x4 (32 bit = 4 byte)

Just an idea...

Ah, also a thing I forgot to mention. It should be this formula:

PhysicalMemOnVCard=dwVidMemTotal+PrimarySurfaceMemory+NeededForDrivers.

The last one is the one I''m looking for, but thanks anyway.
