I apologize if this video has already been posted here. I did a rudimentary look through the posts of the past few days and couldn’t see it.
I’ve been playing Breath of the Wild, Mariokart 8, and Super Mario Wonder.
Breath of the Wild has the same framerate issues as the Switch, Mariokart 8 runs super smooth, Super Mario Wonder has the occasional stutter, but given how new the game is om confident that’ll be resolved with a few updates.
Do not play Breath of the Wild via Switch Emulation, play it via Wii U emulation instead with Cemu.
You get the exact same game but Wii U emulation is easier to run, more well developed and has more options for adjusting framerate and graphics.
You can convert your Switch save to work with the Wii U version.
