I too bashed my head with lutris on some games to the point that i gave up on Linux. Then i tried it again but this time using Bottles and it’s working really fine for me, almost flawless.
Did you try lutris out of flatpak? I don’t know why but this version has less issues. I compared lutris vs bottles and for me the performance of bottles was way worse. (Sadly). Because the bottles ui is much better
I didn’t try that version, I just transitioned to Bottles. I didn’t notice any performance loss though I might compare it just to see what it’s like.
