Really? Seems like it's improved a heck of a lot since its initial announcement, and performance seems beyond anything I expected. I'm really quite impressed with what I've seen.
Actually looks really good on Switch. The devs did a really good job. You can clearly see they put a lot of effort into making the game run smooth and keep as much detail in the game as possible for the Switch. If I was a man that cared for graphics, that would get a pass from me.
It looks reasonably good to me, but of course it looks worse than in other consoles. I would prefer to play it on PC, but I don't see any reason it wouldn't be enjoyed if played on a Switch.
