--- Comment #4 from Sean C. Farley sean-freebsd@farley.org --- I am running it from Epic using Legendary (https://github.com/derrod/legendary) with some environment variables set. I typically use dxvk, but it fails without it installed too.
Basically: WINEDEBUG=-all,+warn legendary launch Sugar -nomovie
From the Legendary log: wine /home/sean/Games/rocketleague/Binaries/Win64/RocketLeague.exe -nomovie -AUTH_LOGIN=unused -AUTH_PASSWORD=redacted -AUTH_TYPE=exchangecode -epicapp=Sugar -epicenv=Prod -EpicPortal -epicusername=redacted -epicuserid=redacted -epiclocale=en -epicsandboxid=redacted
I almost forgot something. If I have OSS enabled and run the game with the -nosound argument, it will not crash. Of course, the sounds are missing, so that is not much of an option.
