Open source project renders your Windows 11 desktop using the NPU rather than the GPU — ‘npu-driver’ can only run at 2 to 3 Hz, targets 30 Hz performance

A developer group by the name of labscommunity has released a prototype driver for Windows 11 that renders the desktop using an NPU instead of the system’s (i)GPU. The new driver is called npu-driver, and the open-source (Apache 2.0) code is available on GitHub. It has been tested on Intel Panther Lake systems, and while it isn’t hitting its 30 Hz performance target yet, it is clever enough to fall back to GPU on request or on any fault.

The reasoning behind the development of this driver may strike a chord with those observing the 2020s processor landscape. “Every new laptop ships an NPU that sits idle while the GPU composes the desktop, runs the browser and, increasingly, runs local models,” notes the npu-driver readme file. “The question this project asks is narrow and testable: can the NPU take over desktop composition, end-to-end, without the applications or the compositor knowing?”

Thankfully, the answer to the question about whether the NPU …
