Microsoft's vice president develops open-source GPU task manager to show which programs are using VRAM
The Windows Task Manager is a relatively basic tool, although several open-source alternatives are already available that extend its capabilities. It displays running processes and shows how many system resources they are currently using, including CPU, RAM, memory, and network bandwidth.
However, it lacks a dedicated VRAM usage display, which is particularly important for today's AI applications. Local AI models rely primarily on the high-speed VRAM available on modern graphics cards. The problem is that the standard Task Manager doesn't provide a detailed breakdown, offering only a rough overview of overall GPU utilization.
To address this gap, Scott Hanselman, a Microsoft vice president, developed an open-source tool called GPU Taskman and made it freely available on Github. The tool shows which apps and processes are using how much of the valuable VRAM. This fills an important information gap left by the standard Task Manager.
GPU Taskman isn't limited to Microsoft Windows, either. It can also run on Linux and, with some limitations, even on macOS. It supports both NVIDIA and AMD graphics cards, although compatibility may vary depending on the platform. The app is available for download on its official GitHub page, along with additional information. GPU Taskman runs on Python by default, but a portable version is also available.
