Hey there, i am trying to play the game on my Linux Mint system but when i run the game, all i hear is main menu music with a plain blue window. At that state computer freezes and i just have to hard reset the computer. /.config/unity3d/THD/Butcher/Player.log is empty so i cannot detect a reason for this issue. my system is not great but with same laptop, but on ubuntu, i was able to run the game smoothly and i am able to run some other light games without an issue. (celeron, intel hd, 4gb ram) Any help...
