The dedicated router and Ethernet connection are probably the biggest things to get right with Virtual Desktop. Even a powerful GPU can't compensate for inconsistent Wi-Fi latency, especially in a flight sim where stutters are much more noticeable. The reduced FOV rendering trick is also worth testing, although the exact benefit depends on the headset, runtime, and settings you're using. I'd change one setting at a time and monitor frametimes and VRAM usage rather than chasing a particular FPS number. One caveat for anyone following this setup: OXR Toolkit is no longer actively maintained, so compatibility can vary with newer OpenXR runtimes and simulator updates. The general principles still hold, but some of the specific settings may not translate directly to every current setup.
