imo if you dont want to upgrade the internal drive of the deck, disable preloaded shadercache and be very particular on what gets installed to the internal drive
a buddy of mine is having issues with Nvidia drivers, is there an easy way to roll it back to a previous version without messing with the rpm-ostree layering
is this hardware-cetric? there is a folk from another sever trying to install this on Nobara, but on his destop, he does't have any Deck-like handheld and wanted to try out this neat feature, he understands that using Steam Big Picture mode is not the same thing haha
