In this video I cover how to install and play Fallout 3, Fallout New Vegas, Fallout 4, and Fallout 76 on Linux using Steam Proton. Step 1. Install The Latest GPU Driver. When it comes to installing GPU drivers on Linux, the installation method will differ depending on your distribution choice. https://github.com/lutris/docs/blob/master/InstallingDrivers.md A great point of reference is the Installing Drivers page of the Lutris wiki as this covers both AMD and Nvidia hardware for Ubuntu, Arch, Fedora and OpenSUSE based distributions. Step 2. Install Steam. Steam should be available to install using a package manager from all Linux distribution’s repositories, and in most cases using a software centre or with Terminal commands. Once installation has finished, launch Steam using your application launcher, apply the update and then sign into your account. Step 3. Enable Steam Proton. To enable Steam Proton for your library, navigate to Steam / Settings / Steam Play and tick both “Enable Steam Play for supported titles” and “Enable Steam Play for all other titles". This will select Proton Experimental as the default Proton build, so restart Steam to apply. From here, install each game in the usual manner, and launch once the installation process has finished. At this stage, all the games should be playable but there are some things that still need to be done as the experience will not be perfect yet. Step 4. Game Specific Fixes / Tweaks. Fallout 3 Out of the box Fallout 3 has two things that need to be resolved, first; the mouse cursor movement is very erratic, and second; the game will be running at a frame rate greater than 60FPS which will causes the game engine to bug out. Fix Mouse Acceleration. The mouse acceleration can be fixed by adding the following entries to the FALLOUT.INI file. [Controls] fForegroundMouseAccelBase=0 fForegroundMouseAccelTop=0 fForegroundMouseBase=0 fForegroundMouseMult=0 The file itself can be located at: .steam/debian-installation/steamapps/compatdata/22370/pfx/drive_c/users/steamuser/My Documents/My Games/Fallout3 Save the file once done. Set 60FPS Frame Rate Limit. To set the maximum frame rate of the game to 60FPS, add the following to the game's custom launch options. DXVK_FRAME_RATE=60 %command% Fallout: New Vegas Fallout: New Vegas has the same issues as Fallout 3, so the steps are the same. Fix Mouse Acceleration. Once again, the mouse acceleration can be fixed by adding the following entries to the Fallout_default.ini file. [Controls] fForegroundMouseAccelBase=0 fForegroundMouseAccelTop=0 fForegroundMouseBase=0 fForegroundMouseMult=0 The file itself can be located at: .steam/debian-installation/steamapps/common/Fallout New Vegas Save the file once done. Set 60FPS Framerate Limit. Again, set the maximum frame rate of the game to 60FPS by adding the below command to the game's custom launch options. DXVK_FRAME_RATE=60 %command% Fallout 4 Fallout 4 should work out of the box, however I recommend that you install and use the High FPS Physics Mod which will allow you to run the game at a higher frame rate without the game’s engine bugging out. Unlock The Game’s Frame Rate. https://f4se.silverlock.org/ Download the latest version of the Fallout Script Extender (F4SE) and extract to the games installation location at: .steam/debian-installation/steamapps/common/Fallout 4 https://www.nexusmods.com/fallout4/mods/44798?tab=files Next download High FPS Physics Fix mod, extract the archive and copy Data folder to the game’s installation directory again. Finally, we need to set the game to launch directly using F4SE by renaming Fallout4Launcher.exe to Fallout4Launcher.exe.old, and f4se_loader.exe to Fallout4Launcher.exe. Fallout 76 Fallout 76 will also work out of the box, but again we can unlock the frame rate and use a custom INI file to improve loading times and performance. Unlock The Game’s Frame Rate To unlock the frame rate of Fallout 76, all you need to do is set the PresentInterval line 0 within the Fallout76Pref.ini file, which is located at: .steam/debian-installation/steamapps/compatdata/1151340/pfx/drive_c/users/steamuser/My Documents/My Games/Fallout 76 Improve Performance and Reduce Loading Times. https://www.nexusmods.com/fallout76/mods/464?tab=description To improve the performance and decrease loading times, we can use the "Fallout 76 Custom INI Performance Tweaks and Improved Load Times" mod on Nexus Mods. Once downloaded, extract the downloaded archive and take a copy of the Fallout76Custom.ini file inside and paste into the following directory: .steam/debian-installation/steamapps/compatdata/1151340/pfx/drive_c/users/steamuser/My Documents/My Games/Fallout 76 #linuxgaming #fallout #proton
