I just checked and realised I'm on 6.16 as well. I don't think the xanmod kernel will solve your problem, it could be worth a try though, if you are desperate.

I have/had the same problem in cs2 (native; so no proton involved) and AMD RX5600XT.
My performance degradation is seemingly fixed for now after my last system update (and switch to latest xanmod kernel (which is at 6.12 I think))
I have an 5600xt and i used to have crashes quite regularly. Disabling hardware accel in firefox helped. Now i only have crashes when playing games from heroic.
Unfortnately all those crashes turned some friends away from linux
You can return games after the 2h return window. Its just that under 2h is an automated refund
The hardest Part in game Jams is always to come up with a good ideal thats easy (or rather doable) to implement in the limited time you have. Unfortunately my friends were of no help to me :( but i think i found something nice
Fortunately trialing an idea is really fast in godot
Check the
manpages, starting withman systemd.time
