Steam-Deck.Shader-Cache-Killer VS Proton

By default, Steam stores these shaders at /home/deck/.steam/steam/steamapps/shadercache/ where each directory is named after the relevant game’s Steam app ID. (For example, 1551360 is the app ID for Forza Horzion 5, whose shader cache takes up 8.9 gigabytes on my Steam Deck!) I wouldn’t really recommend deleting these caches, but you can use tools like Shader Cache Killer or CryoUtilities or Storage Cleaner for Decky to better manage these shaders– or just uninstall the relevant games that take up too much space. There’s tons of YouTube videos out there that can help you with this.

To clear them out you need special programs (careful, when clearing out compatdata on games, as those are the fake windows folders (one per game) also savefiles are stored there, back them up, if they arent cloud synced, also dont delete a compat folder of a random unnamed small thing, because that might be the protons versions compatdata folder, and doing that would ruin the functionality of that entire proton versiion until and uninstall reinstall of that proton version) like https://github.com/scawp/Steam-Deck.Shader-Cache-Killer

if u need clean cache after gaming session try it

Last but not least, some games break, after you change proton versions via force compatibility - they are in the vast minority but it happens. In which case before switching to a new proton version its also recommended to kill compatdata for that game (can be done via https://github.com/scawp/Steam-Deck.Shader-Cache-Killer or CryoUtilities. Make sure to only kill them for the game, and not for unknown or all uninstalled games - as if a mishap happens there and you kill the compatdata folder for an entire Proton install, that version is then borked for every game - so dont.)

Otherwise: Shadercachekiller is helpfull: https://github.com/scawp/Steam-Deck.Shader-Cache-Killer

If I'm not mistaken, supporting MacOS with Proton was the implicit plan before Apple disabled 32-bit support in Catalina. Several people seem to have gotten early builds to compile on Mac with usable performance: https://github.com/ValveSoftware/Proton/issues/1344

Better yet, use a container.

Distrobox[1] automates the process of running distros released in the past decade or so in a container.

For games in particular, Proton[2] (for Windows games) or one of the Steam container runtimes[3] (for native Linux games) might be worth a try.

For a non-Steam game, the easiest way to do this is probably:

1. Install and run the Linux Steam client (Steam account required).

2. Add the game to the Steam library: "Add a Game" → "Add a Non-Steam Game…".

3. Right click on the game, choose "Properties" → "Compatibility" → "Force the use of a specific Steam Play compatibility tool", and choose a version of Proton or container runtime.

4. Make sure the selected Proton or container runtime version is installed (these are available in the Steam library by default; if you can't find them, click the dropdown above the search box in the Steam library and make sure "Tools" is checked).

5. Launch the game from the Steam library.

The "Metaverse" is a complete joke, and among gamers, Valve has a way better reputation than Meta. Why would they want to dilute that brand?

They already have their own platform (Steam), OS (SteamOS), VR headset (Index), their own Windows translation layer (Proton, https://github.com/ValveSoftware/Proton), their own partnership with cloud gaming (Steam Cloud Play using GeForce Now , https://partner.steamgames.com/doc/features/cloudgaming), etc.

IMO: As someone with thousands of games on Steam, there's no way in hell I'd want that linked to Facebook. I think they eventually removed the requirement to have a FB account to use a Quest, but they still require a Meta account. Yuck.

This reeks of Facebook recognizing the Metaverse as the failure that it was and opening it up because it's no longer relevant...

Or Valve's Proton[0], a tool for playing Windows games on Linux.
