Same here. Running Cachy for over 6 months now on my main gaming PC for basically 98% of my Steam/GOG library. Windows 11 is still there for some Fortnite, CoD or Battlefield, everything else is running like a dream on Cachy.
I dealt with Secure Boot for both Cachy and Windows 11. And switched from systemd-boot to Limine manually. I learn so much these days, it feels like exploring a new system back in the days of C64 and Amiga.
