[MDX] Determine video memory size
Author
Hi guys,
I need to determine the size of the video memory from a Managed DirectX application. I know that there is an AvailableTextureMemory property of the Device class, but this does not help, because it includes the AGP/PCIe memory. What I need is the size of the physical video memory on the card. Any ideas how to do this?
Thanx for help

In short, there is no standard way to do this. If you are doing this for caps reasons, you can simply enumerate the device name and lookup the video memory size from that (you need to store this yourself though). However, generally, you don't need this information, as D3D will handle paging of resources in and out of video memory.
I think the WMI interface gives reasonably good results. I've never tried WMI from .Net but it's probably a lot easier than from C++.
