--- Comment #19 from michal.dybczak@gmail.com --- How can I not use Lutris? Game is on Steam and thus installed in Proton. In Lutris I can change runner from Steam (Proton) to Wine. I managed to run some other game that way but it doesn't work for HOMMV from some reason.
Anyway, the game works fine on Intel so I don't have that much initiative to tinker with it further.
