Is there any way to find out which process is using the GPU for intensive calculations? (OpenCL, CUDA, etc? Primarily OpenCL?)

e.g. if you run an OpenCL-powered video transcoder, you'll see nothing in your task manager that tells your GPU is burning through data at a ridiculous rate - though your fans will have kicked into overdrive.

If the reply is driver-specific, I am interested in nVidia primarily.

Turns out Sysinternals' Process Explorer can do this (of course it can, there's nothing it can't do, apparently!).

Process Explorer GPU load by process

  • how can you tell if it is the dedicated gpu or the intel gpu?

Process Hacker, the open source alternative to Process Explorer, also shows the GPU usage.

Press CTRL+I to get the system information Window and click on the GPU Tab, so get a graph with the GPU usage.

  • hover over the high spikes in the graph and you get a tooltip. But the tool also offers a GPU column. Apr 21, 2013 at 18:52
  • @magicandre1981 Worked for me better than Process Explorer; Make sure you select all nodes there; after that you can add GPU usage column to the process list. Make sure you run it elevated. Mar 6, 2017 at 12:02
  • Is this still the best resource?

  • @moondra ProcessHacker also allows you to add the GPU column to see which process use GPU. I prefer ProcessHacker because it is open source compared to Process Explorer. Nov 21, 2017 at 16:29

AMD Catalyst Control Center has an indicator of GPU activity in the Performance section. I would assume nVidia software has a similar output. It's usually associated with overclocking.

Otherwise you can download the free GPU-Z. It includes a GPU Load output.

    Thanks, but you misunderstand my question - I need to identify the process responsible for the GPU load. Apr 21, 2013 at 1:39
  • Ah relied more on the title. I'm going to edit it to be more clear. Apr 21, 2013 at 2:10
