Yea its playable to a degree (somethings i might have to skip or wait for a newer version of cemu, or make a new game dump), i only got it set up last night so i'm still doing tests and tweaking it, right now With Gpu buffer cache Accuracy set to low, i get around 15.00 to 12 fps.
link has a problem of sinking into the ground half way depending on the surface he is walking on,
Im having a serious glitch right now when i clear out an baddy encampment it unlocks a chest in a ingame-cutscene, but its fails to exit that in-game-scene so the game basically just sits there with link staring at the chest.

but apparently other people have got it working in 4k at a solid 30 fps(probably with godtier rigs), which is hilarious because that means an emulator is out-preforming both official consoles.
