About

## Install DayZ

Support for BattlEye anti-cheat for Proton on Linux has been officially announced by Valve on 2021-12-03.

In order to get the game running on Linux, you first have to install the Steam beta client (see Steam's settings menu). Then install Proton Experimental and the Proton BattlEye Runtime (filter by "tools" in your games library). After that, set the "Steam play compatibility tool" for DayZ to "Proton Experimental" (right-click the game and go to properties).

Important notes

In order for the game to actually run on Linux via Proton, the vm.max_map_count kernel parameter needs to be increased, because otherwise the game will freeze while loading the main menu or after playing for a couple of minutes. Some custom kernels like TK-Glitch for example already increase this value from its default value of 64*1024-6 to 512*1024, but even this won't work reliably. Increasing it to 1024*1024 seems to work.

​sudo sysctl -w vm.max_map_count=1048576

Or apply it permanently:

​echo 'vm.max_map_count=1048576' | sudo tee /etc/sysctl.d/vm.max_map_count.conf
