I mean old like Sega Rally Revo. This is not my video, but it sums up my experience playing in deck. The graphics doesn’t feel too old when compared to today’s games and I’m not sure why but I always get above 100fps even i limit deck settings to 60.
Can the Deck do on-demand file compression/inflation to save space?
It can, but it’s not trivial to set up. First you have to reformat/convert to btrfs, then you have to chattr everything, and defrag to do a compression pass on the existing stuff. And after all that, Steam does every download and patch with a preallocate that blocks out the online compression, so you have to subvol and anti-cow its downloading folder to defeat that.
