I agree. For most users all the steps with Proton GE and Protonplus should be skipped

Versions in order of importance: GE-Proton10-34. I had steam installed and used proton before, so you may need to run a windows game with steam first. This should only be required for proton versions and not wine versions

Yooo I got it working on linux first try.

PS: The whole proton GE latest and protonplus thing is just to get a wine runner more likely to work on the first try. I welcome you to try with whatever latest wine version is already installed. 


Here's what I did

Install most recent version of lutris for your distro (Haven't tried flatpak version of lutris)

Install ProtonPlus
Install Proton GE latest with protonplus

Throw RTFM into its own folder somewhere in your Home directory, hopefully on an EXT4 drive, not NTFS.

I put mine in a new folder called RTFM: 
/home/atlas47/Documents/Portable Games/RTFM/

Open Lutris

Set proton GE latest as your default wine runner in lutris

Plus icon in top left to add a game

Add a locally installed game (should be bottom entry)

On the game info tab, select your Runner (Wine, Proton GE)

Also add a game name (mine was RTFM)

On the second tab (game options) select your executable, your .exe (mine was in /home/atlas47/Documents/Portable Games/RTFM/RTFM_win32/RTFM_win32/RTFM-win32/RTFM.exe)

On the same tab, select your working directory as the folder that has the .exe in it (/home/atlas47/Documents/Portable Games/RTFM/RTFM_win32/RTFM_win32/RTFM-win32/)

Hit save, then go find the RTFM entry in your lutris games, then run it. Wait a very long time for first launch and do not stop it before it launches unless unless you want to restart it the whole process.

Game should launch
