--- Comment #37 from evanh evanh@clear.net.nz --- A quick google of D3DKMT nets me this little two year old gem ...
"GPU Used Dedicated Memory and GPU Used Dynamic Memory are detected using D3DKMT calls, and so they are video adapter manufacturer independent. They represent the dedicated (on-board) memory usage, and the dynamic (off-board) memory usage. ...
...
Please note that D3DKMT is an unofficial and undocumented interface, and NVAPI is a properitary non-public interface. Due to the manner of those interfaces they are not documented, not explained by their inventor or designer, and so it's not easy to know anything 100% accurate and specific about the values they provide."
It might worth asking CCP if they really need to be making undocumented system calls.
