I have just upgraded to Windows 11 Home after it was made available to me through Windows Update. Build is 22000.282
Overall, I have had no performance problems using Xplane on my PC running Ryzen 7 3700x (16GM Ram), AMD Radeon RX 5700XT (8GB VRAM).
My one major glitch is that my backup software no longer works (based on a Windows 2003 server) due to security protocols no longer supported.
Other than that, my pain is adapting to the new taskbar layouts and menu choices.
I would not recommend upgrading to Win11 unless you are willing to invest in the learning curve which was higher than I expected. All my installed applications except as above were unaffected.
