>>41347976if I were you I'd check data management for random games that have a 66.6mb update file (excluding smash because that apparently has the same save file size as sword and shield) and turn on airplane mode just to be safe, the slowdowns I got were consistent with other games I have played before (wonky framerate at times in monestary in 3H and my switch is completely fine after four playthroughs of that and Korok Forest fucking framerate in the ass, don't know what is going on with monestary and hammerlocke, but I think the switch just doesn't like detailed grass for whatever reason)
