Installed the game today, but cant get through tutorials because my game crashes instantly when the gameplay starts, or even in the loading screen before it. I attached a short video about how it plays out.
Doesnt seem to matter if im on windowed/borderless/fullscreen, both vulkan and dx11 end up in the same situation.
Edit:
Figured this one out so ill write out my debug process for others who might encounter this.
Started by adding launch option PROTON_LOG=1 %command% to create log file
From the log file, found the spot where bunch of error messages start popping up
Found this, checked what value this mapping has currently
sudo sysctl vm.max_map_count
vm.max_map_count = 65530
Thats nonsense, increased it to
sudo sysctl -w vm.max_map_count=262144
After that, game runs without issues
Note that this command only changes it for current session, permanent change would be modifying this value in sys/conf files.
