There is no headroom because it was poorly made, simple as that. If you have games that are more intense, have higher IQ and can get 1080p and or 60fps, then it is clear this game could as well. I haven't said anything about the current form, because obviously if it could in the current form it would.
Yes sure being cartoony doesn't automatically make it light. But comparing it to other games (photorealistic or not) I don't see anything technically outstanding in this game.
I don't see any sign of it being poorly made from a technical perspective; it's not like its has a bad framerate, rampant bugs, or anything like that. It simply makes the common UE4 tradeoff of a lower resolution.
It may not be a top-tier graphical showcase, but we can't really write off the Switch version's accomplishments by saying it's "not demanding" when we're talking about a game that runs at 900p on PS4.
Bet with Liquidlaser: I say PS5 and Xbox Series X will sell more than 56 million combined by the end of 2023.
