steamos-btrfs VS Steam-Deck.Shader-Cache-Killer

Seems theres some work needed for it to work with btfs, perhaps someday. It seems it can work with btrfs, but there can be some issues. https://gitlab.com/popsulfr/steamos-btrfs

I followed a guide to install BTRFS support and successfully converted my /home directory and SD card. However, I encountered an issue where all games using Proton stopped working. I attempted to resolve this problem by changing the Proton version (stable, experimental, GE) and reformatting the SD card to Ext4. Interestingly, native Linux games are functioning correctly. Logs aren't really helpful:

did you properly set up the btrfs script on the Deck in order to do this or did you just reformat it as btrfs without any preparation?

i use btrfs for my steam deck windows dualboot and it works great for storage sharing. I already ran this script to convert the sd card a while ago and it worked perfect, but now I want to do it again and this time make use of the script's feature to have a btrfs /home so i can access the ssd's storage on windows. however, when I run the script again, it opens a window asking "select the rootfs devices to install into" and a bunch of long file directories i don't understand. have i just missed the boat for a btrfs ssd, and i shouldve done it at first setup?

Ahh, that's a huge peace of mind! Which method of setting up btrfs would you recommend? I found the old btrfsdeck repo, which pointed to this new one.

Btrfs is a filesystem which supports copy on write and filesystem-level compression, both of which combining to potentially very large storage space savings. If you're interested, there's a program which can convert the Deck's /home partition to btrfs here: https://gitlab.com/popsulfr/steamos-btrfs

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
