Got a Switch 2 on launch day. Been going through some of my Switch 1 games that had poor performance on the Switch 1 (e.g. Deadly Premonition Origins & the original Shin Megami Tensei V) and performance is night & day. All they need is some slight code optimisations, a patch sent out and they'll be right as rain (although for those two I doubt that will happen at all). Won't be as easy for CPU-bound Switch 1 games since they'll require heavy code re-writes to take advantage of the new hardware (e.g. Dragon Quest Builders 2). Currently playing Breath of Fire 1 on Switch 2.
