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!

    I managed to squeeze 24-30 fps in my deck with a nice experience overall… but audio is still choppy, how did you manage to fix it?

    Basically I use Fidelity FX with a lot of sharpness, resolution scale to 50% and a few of the patches in the wiki, I can share my settings if you need it
