The Legend of Zelda - The Wind Waker on Linux4Tegra Ubuntu 18.04 for the Nintendo Switch. Running on dolphin-ishiiruka with Vulkan at 720p.
Skip to 8:30 if you just want to see the gameplay. The first half of the video is showing you that I'm actually on a Switch, and then there's a few minutes of the Wind Waker intro. Running fullspeed (30fps) at times, while usually hovering at ~25fps. Some dips to ~20fps as well.
This is as far as I've played. I'm sure performance will degrade as you get to more demanding areas. But it's a really nice start.
