Comment gérer les villes: Skylines II sur Linux utilisant Proton

Ce guide montre comment faire fonctionner le jeu et obtenir plus d'espace Swap en utilisant xrar sur Fedora Workstation. 38 et quelques trucs et astuces pour pouvoir jouer au jeu avec de meilleures performances (ou pas du tout).

System Specs

Proton version and Steam arguments I use

These are the Proton versions I tested:

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

Get more Swap Space

• 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 =
• Après le “= ” You can add with how much swap space you want relative to how much ram you have. Exemple:[zram0]
  zram-size = ram

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

  • You can add: <ram / 2> (sans<>) to set your swap to half of you ram
  • You can add: <ram> (sans<>) to make your swap the same size as the amout of RAM
    Disponible
  • [Pas testé] I think you can add: <ram * 2> (sans<>) 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:
