Task Manager displays minimal GPU activity during maximum workload.
Currently I'm working on Folding At Home, though it might not be 3D. I'm facing the same problem in Blender (render issues) and gaming.
It's unusual, but the task manager can sometimes handle this. Consider trying Hwinfo64 to check consistency. The free download of HWiNFO Software | Installer & Portable for Windows, DOS is available.
