If you’ve ever tried to figure out which of your applications is hogging your GPU, you know that Microsoft’s Windows is about as helpful as a chocolate teapot. Sure, you can peek at the Task Manager, where you'll be greeted with vague numbers and an overwhelming sense of confusion. Want specifics? Good luck with that buried treasure of per-process GPU memory readings—because why make things easy?
But fear not, for Scott Hanselman, a Microsoft bigwig with a knack for handy utilities, has come to the rescue with a shiny new toy called gputaskman. Yes, the name sounds like a rejected superhero, but this tool actually tells you what your GPU is doing—and why it’s crying for help.
While NVIDIA users have a slightly better experience with their Activity Monitor—which only names the offending applications without giving a backstory—gputaskman goes full detective mode. It spills the tea on GPU usage, VRAM consumption, temperatures, power draw, and even the nitty-gritty details of individual processes. It’s like a “who-done-it” for your computer’s graphical capabilities.
As if that wasn't enough, gputaskman also throws a spotlight on local AI processes. It identifies what those fancy neural networks are up to, showing you details like model weights and layer counts. It’s like giving you a backstage pass to the AI show.
I gave it a whirl, and while it mostly performs as expected, I did encounter a couple of quirks. For instance, GPU temperature updates sometimes freeze—really living up to the “experimental software” label, huh? But hey, at least it’s not crashing your system while it does so.
Available for Windows, Linux, WSL, and Apple Silicon Macs, gputaskman is out there waiting to enlighten your GPU usage experience—just be aware that it may not be 100% stable yet.
Keen to dive in? You can snag gputaskman from Hanselman’s GitHub repo and give your GPU a little pep talk.
So there you have it, folks: no more confusion about what’s making your GPU sweat. Now if only we could get a tool for figuring out what Windows actually does with all the updates.
