I didn’t expect it would enhance framerate at all without a game patch to be honest.

I was expecting something like new 3DS, where all games that were not specifically patched for it ran exactly the same. But I guess the difference is that new 3DS must have run in pure hardware old 3DS mode for those.

I felt DQB2 was already somewhat playable, but I probably never did very crazy builds. I remember people warning that destroying mountains on the main island for example was a very bad idea, because they were supposed to limit how much of the island the game had to render. Maybe I should check my old island on Switch 2.
