Add GPU tab
In this article about Windows 10, you can see this image of the Windows Task Manager and the text:
Task Manager now has a neat GPU tab and GPU information in details view to show how busy the GPU is. In multi-GPU systems, it shows which programs are using which GPU.
Some GPUs offer this capability on Linux, as can be seen in gpuvis, a full-fledged analyser debugger. I think reporting parity with Windows would be a good target to aim for.
