So I set up my system with btrfs in the last days and I converted two external drives (from ext4) (mainly game) and run defrag and balance, because it was mentioned in a guide to compress the existing files. Was that a bad idea? Didn't read anything about duplicates.

Do you have MangoHud installed? Last week I couldn't run any proton game on my system until I uninstalled it/ removed the MANGOHUD=1 variable haven't had this problem before, but something broke. Proton and wine were stuck at launching, no error messages/ logs, etc. drove me nuts.

I am on arch and use both KDE+Wayland/X11 on my 3060ti and for me wayland still has lots of visual glitches, some programs flicker, sometimes the plasma bar is frozen, etc., etc.. Gaming is hit or miss. But I can say, the things that do work are a lot smoother than on X11.

My Sony noise cancelling headphones (XM3). I love them and use them every single day. And also my wall mounted pull-up bar.

Got something similar yesterday, but for KDE-Connect from F-Droid. Downloaded the Play Store version instead.

Pretty much this. And they are still too expensive.

The steam version works just fine too, if someone is using it. I love this program. Use it in conjunction with krita.

On the weekend I was playing Cross Code but I put that aside for my vacation.
I don't have much time after work at the moment, so I found a really strange game called Sally can't sleep. Digging the atmosphere. Gameplay is a bit wonky and frustrating but I love just to roam around. But I can imagine that it's too strange for most people.

Some games I recommend:

Alina of the Arena: A roguelike deckbuilder game. It has turn based tactical battles. There are lots of cards and builds you can try, but there is a fair amount of randomness to it. So you have to go with what you get.

Unreal Life: A really strange, surreal adventure game with a talking traffic light. Great visuals and music.

YumeCore: Just a short little game where you beat up people in a hospital. Why? Why not?

Flood of Light: Great little game with pretty much one core mechanic (direct lights). The Engliah translation isn't the best, but I really liked the atmosphere.

Brotato: Is it a hidden gem? I don't really know, but it is a fun "Vampire Survivor"-like game and a huge time sink. Great shop mechanic and large amount of characters and items.

I don't like always online games.
Some years ago a friend asked me to play Diablo 3 together, so I bought it and tried it in singleplayer to get familiar with it, since that was the first time playing a Diablo game.
I got very hard lag - in a singleplayer session and lost the connection to the server several times.
It was such an awful experience that I couldn't bring myself to play it online anymore.
