start of the game is bugged, even if you manage to get past it by downloading save off the internet the first puzzle is uncompletable because of some wine shenanigans. borked.

${STEAM_RUNTIME}/scripts/switch-runtime.sh --runtime="" flatpak run net.lutris.Lutris lutris:rungame/penumbra3 # %command%
I simply indicated in Lutis the location of the executable file of the Linux version of the game installed via Steam and selected Linux in the Runner field
Rare drops to 45 FPS have been seen on the last levels
• The native Linux version, when launched normally via Steam, crashes when level is loading.
• When forced to use Proton, the game does not crash, but shows a black screen when loading a level. This is fixed by disabling Post Effects and lowering the Shader Quality to mediumin in the graphics settings, but the scripts remain broken in the game, the cutscene of the first level gets stuck in an endless loop on a beeping computer at the very beginning.
• The only working option was to run the native Linux version of the game through Lutris. This saved the game from crashes, broken scripts, and allowed you to enjoy the graphics in maximum quality. I was able to completely complete the game in this way without serious problems, only at the end of the game rare drawdowns up to 45 FPS began to appear.
• Also, in order to launch the game from the original shortcut, and for Steam to count the time spent in the game, I added the above command in the launch options, which replaces launching the game through Steam with launching through Lutris, in which the value "penumbra3" after / corresponds to the identifer field in game shortcut configurations in the Lutris library.
• As far as I was able to find out, the native Linux version crashed when launched through Steam, since Steam OS defaults to Mesa Library is built with compiler optimizations applied. And it seems that Lutris uses some other custom Mesa Library, so the game does not crash when launched through it. Unfortunately, I don't know of a way to change the Mesa Library in the launch options of the game, maybe it can be done somehow more gracefully, without using a Lutris layer.
