Linux Mint + Steam Play(Proton) not working at all

[SciSan]

When I open a windows native game (and get the notification it will run through the steam play thing), the game seems to start for a second, but it shuts down immediately. This is the case for every Windows game I tried on my Linux mint, so I wonder how to fix the issue.

I'm not really sure which games you're talking about but to make sure they are currently working with Proton check www.protondb.com to see if those games are currently supported.

I'm talking about all the games that are not Linux native - those supported on that list (www.protondb.com) and those that are not. Nothing works, expect the Linux native games that naturally don't need the Steam Play

first off, know your logs. you can use "tail -f /tmp/dumps/$(whoami)_stdout.txt" to read the last few lines of the steam log, and it will also auto-update when the log is updated. run it before launching the games that you wanna troubleshoot. there's also a logging functionality in proton. right click on the game in steam -> properties -> set launch options, and set it to "PROTON_LOG=1 %command%". this will log the wine debug information to ~/steam-$appid.log.
second, make sure that your drivers, but more importantly your gpu supports vulkan. lack of such support may be the cause, in which case try also setting "PROTON_USE_WINED3D=1" (before the %command%) in the launch options.

Thank you, I'll look into these. It seems to be that lack of Vulkan support on my old GPU was the critical factor, as the "PROTON_USE_WINED3D=1" worked on few games I tried so far.

in such case, instead of setting the launch options for every game, you might wanna set up proton to work without such hassle. go to it's install directory, you will find a file named "user_settings.sample.py". copy it to "user_settings.py", then open the copy in any editor and uncomment (remove the leading # sign) the lines like "PROTON_USE_WINED3D" or something like that. you can also copy the format to set some other variables. also, if you're using the open-source drivers, you can try gallium-nine for an extra fps boost for directx9-based games.
