It's a good game but...

Why is the optimization not that good? I'm in a potato pc and found out about this game via tiktok and thought "huh, that looks fun. Let me try it". So I did, but I was surprised at how my pc run poorly with its default settings and had to resort to the lowest settings with the lowest resolution scale so the game can run ok. It's a skate game, graphics shouldn't be that demanding, right?
