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!
Was it even playable in rpsc3? Last I checked it on my pc it couldn’t properly render most of the post effects
In my experience Pacific Rift was pretty good after tweaking. Apocalypse was a little more rough but I found it mostly playable. And I have a pretty modest/old build.
