Yeah, 60 FPS isn't even necessary for Pokemon. Scarlets problem is stability. Breath of the Wild ran at a smooth 30 and that was a much more difficult *action* oriented game.
A consistent 30 FPS is all Pokemon needs.
As many problems as scarlet and violet have, only one really bothers me at all, and that's the fact that online mode is completely f****** unusable. The vast majority of times I try it to go on a Tera Raid or trade with someone, it tells me that I couldn't connect. I really want a larvitar because it is a Scarlet exclusive, and I tried trading for one earlier, and the game just wouldn't let me trade it.
