Since SteamOS 3.5 finally released into stable, I’ve been looking forward to try out PS3 emulation on the Steam Deck, especially the Uncharted series & MGS4.
Long story short, performance was rather subpar, with frequent FPS drops.
Looking around, I came across this post on Reddit:

After applying the tweaks referenced there, I really did saw a boost of a few more additional frames, but the real improvement is that the frametimes become more even, resulting in noticeably less stuttering.
With a 50 % resolution render scale, Uncharted 1 can be considered playable on the Steam Deck, IMHO.
Hope these tweaks help you guys out, too!
Imagine Sony sitting there, planning out every PS5 game they’ve ever made as ports to PC EXCEPT Demon’s Souls.
That’s including Sackboy.
But not Demon’s Souls even after Dark Souls became a massive hit on PC that blew everyone involved away and led to the incredible success of Elden Ring.
That meeting where they had to pick which launch title to port and they chose Sackboy over Demon’s Souls was one where a lot of money was lost.
