exactly.
the Witcher 3 is a good comparison point. the game looks crazy good on PC is fully open world with no barriers blocking your line of sight... yet it can run on the Switch by dropping draw distance and other settings.

so what exactly would a game look like that is designed for SSD? how would you improve from something like GTA 5, The Witcher 3 or Red Dead Redemption 2? RDR2 especially already has so little noticeable pop-in on Xbox One X while looking crazy good. what could an SSD improve from there when it comes to leveldesign?
and stop with that Horizon flying across the map shit. that is 100% an Engine issue not a hardware issue, since so many games have fast vehicles that allow you to fly across detailed open maps. games made with the Rage Engine, Apex Engine or even Call of Duty's engine can do that with ease now.
