How to find GPU memory(video memory) using NVAPI

Question

I am using NVAPI, I can get some performance data by calling this function:

NvAPI_GPU_GetDynamicPstatesInfoEx

But don't know how to get video memory usage. I find some c# codes call this function to get it.

NVAPI.NvAPI_GPU_GetMemoryInfo

But there is no the same function in NVAPI.

Any idea?

that C# code does use nvapi.dll, GetDelegate(0x774AA982, out NvAPI_GPU_GetMemoryInfo); — colin lamarre, Aug 23 '16 at 05:03

Does it have to be in NVAPI? If not, check out Nvidia PerfKit: http://developer.nvidia.com/nvidia-perfkit

In case somebody still needs this, you can use this library:

Find the right GPU using the NvAPIWrapper.GPU.PhysicalGPU.GetPhysicalGPUs() static method.
Use the NvAPIWrapper.GPU.PhysicalGPU.MemoryInfo property to get the total memory, available memory and other information relative to memory.

I think for what OP asked you are using NvAPI_GPU_GetPhysicalFrameBufferSize (which is call from nvapi if somebody need it) if I checked the repo properly... – CJ_Notned Apr 28 '22 at 11:45
