I got it to run under Lutris with "lutris-GE-Proton7-35-x86_64" and with "Disable Lutris runtime" under "System options". After starting the game, go straight to graphics settings and switch from DirectX12 to DirectX11, then quit and start over.

The game seems to work fine, I experienced no crashes after a couple of hours playing. The only problem is that the game occasionally freezes for a couple of seconds, mostly during cutscenes, but also when visiting a new region of the island for the first time. Not ideal, but definitely not a deal-breaker.

I also tried Wine 8.20 and Proton 8.7, but then the game locks up right after the opening logos, and you have to close it from task manager. if you don't switch to DX11, it locks up after creating a new profile.

I'm trying to get it to launch atm but only got lutris-GE-Proton8-25-x86_64 on my new installation.

So how would i go about installing lutris-GE-Proton7-35-x86_64? New to lutris - could you provide any pointers?

Open Lutris, click the three horizontal line icon near top right, choose "preferences", then in the tabs on the left click "Runners", scroll down to "Wine", and click the round cardboard box icon on the right. A dialog will open up that lets you install various lutris, wine, and proton versions.
