Query information from NT Handles of shared D3D11 Textures

tl;dr: you can't. Only D3D12 and Vulkan resources expose API to query it's physical size

Looking into using the gl extension EXT_external_objects_win32 stumbled upon this <size> parameter in glImportMemoryWin32HandleEXT when using a D3D11 resources

tl;dr: Use 0 as size when using HANDLE_TYPE_D3D11_IMAGE_EXT / HANDLE_TYPE_D3D11_IMAGE_KMT_EXT

the driver implmentation will figure out the internal size of the resource. This size would be alignedWidth * alignedHeight * Bpp where alignment varies depending of the graphics card vendor, model and driver version.

To give some context, here are some values from my NV card with updated drivers
