I had that issue but setting it to 1750/844/1600 ReverseNX while docked made it fine. Handheld I'm using the 720p mod so I've just accepted 30fps with a tiny overclock in GPU
Bit of a long shot but is there any way you can make this work through Rosalina? I'm using mikewii's plugin loader so I can't use codes outside of Rosalina in game. Probably not possible but no harm in asking. They did charge blade dirty in this game
Is there a way to get this to work with Luma 10.1.2? The 60fps codes do work but there's random freezing every few minutes and the only fix I've found is using Luma 9.1 instead
