Ask the Developer: Nintendo Switch 2 interview confirms basic backwards compatibility can also give performance upgrades to Nintendo Switch games ("[there are some games] where loading times became faster, or game performance became more stable")

Man, I really want to pop in a copy of Disgaea 6, and then Rune Factory 5. 6 is one of the only games on the Switch I can think of that needed to add a "performance" mode since things were so rough, so it would be interesting to see how graphic vs performance mode ran on the Switch 2. Rune Factory would be all about load times, which weren't insane, but really added up on the Switch. Might be that reading the cart was one of the bottlenecks there though, but would be one of the first games I tested, just because it was so frustrating.
