I wasn’t having many issues to begin with, but with the introduction of explicit sync into Kwin, and driver improvements throughout the 555 beta series, it’s been just about perfect for me.
The only issue i’ve encountered so far is the panel freezing sometimes. Submit a bug report to both KDE and Nvidia, they’re working on it.
I’ve returned to the game too, after a fairly long break, and ended up settling on Thuldor’s preset. I love Simonrim, so it saved me the time on putting it together, but all the newest fixes/modernization efforts are there too. Strongly recommended. The leveling process is completely different, and that’s something I haven’t tried before. About 60 hours in, it’s really damn solid
