theres a lot of factors that impact tolerance. for example motion blur. I personally hate a lot of post processing effects, so having motion blur off makes low fps gameplay pretty jarring.

Currently im going through pokemon violet, not on my switch, but on emulation, and the 30fps is really rough, and the 60fps mod has tradeoffs. If im complaining about ot on emulation on a reletively high end pc, I couldnt even imagine how bad the performance was on native hardware, given it was one of its biggest complaints.
