Since the subreddit got killed, I'll post the settings I'm currently using. I'm getting a mostly-ok 30fps, with dips down to 20. Definitely playable. Shrines can spike to 50-60 fps, which is nice. If anyone has tweaks to improve performance I'd love to hear it.

CryoUtilities 2.1.4 Default Settings
I apologize if some of this is superfluous or if I missed something, its been a couple weeks since I set this up. I got these settings from a post on the subreddit and tweaked them a bit. I'd love to credit that user, but subreddit nuke :(
Thanks for sharing! I've been meaning to get TotK going on my deck, and I'll be saving these settings for when I go back to it.
Biggest thing holding me back right now is I'm having trouble pulling my save file off of my switch, for some reason it's the only game that doesn't show up in the save file manager.
