Remember that in 2023 RedHat restricted access to the source code of RHEL packages, which had a big impact to lots of server distros. This article explains really well why that's problematic:
HTTP3 benutzt QUIC, was eine alternative zu TCP sein soll. Ein Grund dafür, warum QUIC aber nicht ein eigenständiges Protokoll neben TCP und UDP ist, so wie es an besten ins Schichtenmodell passen würde, ist wohl dass einige Firewalls alles blockieren was nicht TCP oder UDP ist, denn das kennen die nicht und es ist ja überhaupt nicht vorstellbar, dass irgendwann etwas anderes verwendet wird.
I think it was obvious that it was never going to be a free game again. The problem is making it look like it's free to play and then hitting the player with a paywall after a few games. Also, the subscription model is shitty. I would readily put down a onetime payment for something that works as least as good as the web version, which is a lot more polished than the free alternatives I've seen. But I refuse to buy into this subscription model.
You have already done most of what I would do, but here is my list:
Try another Proton version (in my experience Proton 6 seems stable and sufficiently different)
Check ProtonDB if this problem is known
Read the logs in the command line output
Try both steam-native and steam-runtime (maybe this is only an Arch thing?)
First back up, then delete the entire protonprefix (~/.local/share/Steam/steamapps/compatdata/<GAME-ID>). THIS WILL ALSO REMOVE ALL SAVEFILES OF THE GAME!
Use an Xorg desktop environment instead of Wayland
Ads disguising themselves as regular posts (e.g. the "LPT") is bad. It gets worse when someone screenshots and reposts the ad, presumably even for free. But why does the R****t ad make it all the way to Lemmy!??
Only using Lemmy. R***it has abundantly convinced me to never look back there.
