I have had numerous cases where a non-Steam game would run perfectly through Steam with Proton but the same game wouldn’t even launch through Lutris, even though I used the exact same Proton version. How are they different? Is there anything that Steam does in the background that Lutris won’t?
I’d love if anyone could shed some light on this for me.
Proton is Valve’s version of wine running inside a container specifically made for Steam, while Lutris is only using wine.
And the versions being used by Lutris and the version being used by Steam are not the exact same thing. If you use GloriousEggroll for example there is the proton-ge-custom repo for Proton, which is the one Steam uses, and the wine-ge-custom repo that Lutris uses.
I’m not even sure that the latest “GE-Proton8-14” and “Wine-GE-Proton8-14” are actually equivalent to each other. They were released two weeks apart and might be based on slightly different wine and/or dxvk versions since they are using whatever the bleeding edge git commits are, rather than actual stable releases (i.e. using commit #ABCD1234 instead of release version 1.2.3)
