I got it to work perfectly from this guide: https://piped.video/watch?v=_PLEm1v9bzw Works really well high fps and all. Something I dont think the guide mentions is updating the battle eye runtime using the one from steam.

Tried a couple times - installing via lutris, or proton, played with some winetricks etc. Eventually the launcher worked, then more tweaks for the game to load. But then gave up once it crashed to desktop loading the game every time.

Its a shame, reasonably fun game overall.
