I'm currently trying to get Transistor to run.
EndeavourOS, Nvidia gpu, and I have the Windows version that was free on Epic that one time, so ideally I'd like to run it through Heroic.
According to PCGamingWiki, it can be run DRM-free with the -AUTH_LOGIN=unused launch option, so that's what I'd like to do.
EDIT:
I want to be able to sideload the game files
Looking on ProtonDB, people mainly suggest setting the compability to Windows XP, and it seems to run best with Proton Experimental. One report mentions adding it to Steam to launch it there, but it's all the same for me:
Quick blackscreen with the game trying to launch, and then it crashes back to desktop.
Did anyone get it to run recently? Any other ideas I might've missed?
Remember that experimental is a constantly changing version. When you see users suggesting you set a game to use proton experimental, always check the date, because more likely than not, experimental no longer refers to the same experimental they used.
I'll test this out and get back to you on whether I can run it.
I installed the windows version from steam. The game does not run under proton 8.0-5, but does with the current versions of experimental and Proton-GE from the AUR.
I did not need to set windows version to XP, or do any other kind of extra fiddling. So all you should need is to set the no DRM launch option in heroic to allow the Epic version to run.
If you haven't installed that Proton-GE package from the AUR, I suggest doing so. It's been the only "custom" proton version I've needed for ages, it gets updated when a new version comes out and makes itself available for selection in both Steam and Heroic, so it's a very set and forget way to use the GE versions of Proton.
Shot in the dark - Is there any chance the game data is on a shared NTFS partition? The start > blackscreen > dead pattern often happens if you happen to be accessing the game data from an NTFS partition, but that part of the error message is super deep and not really obvious.
After some more trial and error, I think I've come to the conclusion that either the Epic Version can't actually be run DRM-free, or I'm somehow being too dumb to copy paste the launch option that allows it to.
