They were just the default settings when I setup Emudeck a week or two ago. I did setup RetroDeck too as I liked the more containerized nature of it, but it seems to run an older version of Yuzu (has a different, lower number in the window name) and even when I mirrored the settings of my Emudeck version it was pretty stuttery and crashed at least once.

But I can look at my settings and share later today.

Not sure what the FR is, but Tears of the Kingdom runs flawlessly for me on the OLED Deck.
