Open-source GPU task manager reveals exactly what's eating your VRAM
A new open-source GitHub project called gputaskman has been released by Microsoft VP Scott Hanselman.
Microsoft VP Scott Hanselman has unveiled a new open-source project called gputaskman, a GPU-focused task manager that can reveal per-process GPU usage, VRAM consumption, active runtimes, and more stats across Windows, Linux, and macOS. Designed to get insights into where GPU memory is being allocated, gputaskman also provides AI/LLM task-specific information.
In a tweet, Hanselman notes that his desktop windows manager is the most VRAM-hungry app on his RTX 4080S system, and selects it in the tool's list to show detailed breakdowns. The tool was tested by the author, who found no tasks using the discrete GPU in their laptop. After running the Unigine Valley GPU benchmark, they observed live-streaming charts displaying GPU load, VRAM use, temperature, and other metrics.
The gputaskman tool is available for download on GitHub under the permissive MIT license, and its developer hints at future expanded GPU monitoring capabilities becoming standard on Windows.
