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!
Any luck with God of War 3 ?
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
btw make sure to reenable SMT for Yuzu, they seemed to have fixed the performance drop that required us to originally disable SMT
Did anyone try original Demons souls in RPCS3 on the deck already?
Do these tweaks just effect Desktop Mode; PowerTools already allow CPU scheduler changes
I did these tweaks before updating to 3.5.5. Do I need to do it again now that I’ve updated?
I can’t even get non steam games to run after the update.
I’d love it if someone could tell me if infamous 1 and 2 are in a better state
