Divinity: Original Sin 2

No, I did not read that. It's not there.

Oh damn, weekend wasted.

Interesting to see Bioshock 2 Remastered on the list. I just completed it with Proton 5.13-6, I've just disabled esync, and it was running pretty solid. During my ca 20 hour play through (incl. the DLC), I had like 3 crashes.

Oh, and if it crashes, and even created a core file in the binary's path, make sure to delete the core file, as the game won't start otherwise anymore. Same is true for Bioshock 1 or even the Borderlands games, so it seems to be a 2K thing. It even won't start on Windows anymore if a core file is present, but Windows normally doesn't create a core dump on a crash :D
So it might side-load something on start from a core file.

Hey Corben, thanks for the heads up. How would I go about finding this core dump file if I needed to?

What was there in newer Wine that you were waiting for? Most stuff that is important for gaming gets backported.

Lets see if it fixes Postal 4 that became dodgy with the latest update March 1st, as it fell over with the Epic C++ Runtime error, earlier version fine & dandy.

I was stuck in Skyrim Dragonborn with a glitch. With the new Proton based on Wine 6.3 now it works and i can progress...
