Looking Glass
Looking Glass provides low-latency display and input for using Windows from a Linux environment.
About Looking Glass
Looking Glass is open-source software that brings a Windows desktop into a Linux window with low-latency display and input. It uses a native Linux client with a Windows 10 or 11 machine running under KVM/QEMU, so Windows software can be used without leaving Linux. PCI passthrough is recommended, not required. It suits Linux users who want to run Windows software without dual booting.
Pricing is not clearly stated.
