It works and it's fun!
Multiplayer penguin game (Linux themed Fall Guys)! lol
force_vk_vendor=-1 %command%
Running with Intel graphics requires spoofing your gpu vendor with force_vk_vendor=-1 for now as there's no XeSS support on linux
Sometimes the game refuses to launch for unknown reason (no logs), removing it's compatdata folder to regenerate the proton prefix fixes the issue.
The online latency issues can be fixed by switching the ingame Automatic region chooser to your own region.
Cant invite friends with error 110210, most likely because playing through steam and not epic.
Only issue was the games matchmaking: I was queueing from North Europe, Finland: 1st match: solo queue ~2mins ~300 latency 2nd match: solo queue ~2mins ~365 latency 3rd match: solo queue ~2mins ~250 latency here at the start of 3rd map i was disconnected with error 100200 failed to connect to the game server. 4th match: solo queue ~1.5min ~360 latency. It was still playable with these latencies but there was a lot of rubberbanding esp. when dashing.
Worked fine, no issues
The Epic Games interface does not open to invite friends.
