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!
Given the master collection; don’t hold your breath
Maybe volume 2 and maybe the complexities of getting 4 right has meant they phoned in volume 1 but most likely it won’t be there and if it is it will be shite lol.
even if it’s a shit port it’ll still be much better than being stuck emulating it (though im sure rpsc3 will make great leaps in a year or two in terms of performance) or buying a ps3 to play it lol
