I'm sure they are, but it's much less noticeable than the handheld ports of things used to be. Having played many hours of Star Wars Battlefront II on PS2 and original Xbox, the PSP versions of Battlefront (II, Renegade Squadron, Elite Squadron) had some obvious compromises but were at least very similar to play. Then I tried the DS version of Renegade Squadron and the gameplay was almost unrecognizable from the others, which still disappoints me to this day.

Granted, I'm playing Skyrim and Portal 2 on Switch Lite so I can't see them on the TV and compare them at the same size as the PS3 versions of those games, but Skyrim at least seems to suffer much less lag and visual glitching than the PS3 version. I don't have any newer console to compare with so I'm happy!

My laptop runs Kbby Lake and Intel HD 620 and can't match the Switch's 30 fps perf. It's incredible what it can do. The 3070 that runs 220+W on my desktop is hard to replace ore minituarize.
