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:

https://www.reddit.com/r/SteamDeck/comments/16ydaoz/mgs4_on_rpcs3_with_full_visual_effects_on_the/

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!

    Are Motorstorm Pacific Rift and Apocalypse playable now ? I cannot test right now, I probably will one day, but I’m wondering if anyone tried recently (with the steam update and all).

    What about Azura’s Wrath? That game was completely unplayable with the intro sequence being literally 1fps.

    I havent tested PS3 as much, but the switch emulation has also improved a little

    THPS 1 + 2 is more stable in some levels

    Pokemon Violet used to run at around 80% speed with a lot of frame drops. Now it still has the frame drops but it seems to be running at full speed

      Switch emulation has been pretty good in my experience. The weird differences in performance have been when I run games in desktop mode compared to SteamOS. Some work better in the former and others the latter

      Is there even a need for THPS 1 + 2 emulation now that the game has been released on Steam?
