Cities: Skylines II – How to Run the Game on linux Using Proton [FEDORA]

GE-Proton-8.21, Proton 8.0-4 and Proton Experimental.

The one I ended up using is Proton 8.0-4

These are the args i use to run City Skylines II :

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia gamemoderun %command% -preload +fps_max 144

Note that __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia only applies to Nvidia GPU if not customized. You can also change +fps_max 144 to suit your monitor’s max refresh rate

• First check if zram-generator-defaults is installed or install it by running:

  sudo dnf in zram-generator-defaults

• Then edit /etc/systemd/zram-generator.conf to change how much Swap space you want with for
  For exemple :

  sudo nano /etc/systemd/zram-generator.conf

• You need to add in the file:

  [zram0]
  zram-size =

• After the “= ” You can add with how much swap space you want relative to how much ram you have. Example:

  [zram0]
  zram-size = ram

  Here are different option if you want more/less swap:

  • You can add: <ram / 2> (without<>) to set your swap to half of you ram
  • You can add: <ram> (without<>) to make your swap the same size as the amout of RAM
    Available
  • [Not tested] I think you can add: <ram * 2> (without<>) to make it double the installed RAM
• Reboot your computer and, Voilà !
  You can go check in system monitor for the amount of Swap Available:
