@bossmeran has a point. The decision calculus is now impacted by Switch 2 thanks to diminishing returns, scalability, and DLSS.
Resharing this, comparison between Ratchet and Clank from PS5 (top) and Steam Deck (bottom).
One is obviously better. If you scrutinize the image you can identify the aliasing, lower texture resolution, and so on. If you blow it up on a 4K TV it will be more apparent. The Steam Deck version also runs at half the framerate.
-- but on a tablet screen or living room viewing distance, how noticeable is all of this to the 'layman'? Even if they identify the top one as better, if you tell them the device spitting out the bottom image can also be carried in your backpack, they'd start to weigh the benefits of the portable device more seriously.
In my experience, 'low' or even lower than low settings don't really result in potato graphics anymore, and I expect a lot of the issues that plagued Switch 'impossible' ports to be alleviated by the increased CPU and RAM as well. Then you introduce DLSS into the equation and you start to muddy the waters more.
There will still be games that miss the Switch 2, or are ported and absolutely push the system and bring it to its knees, probably resulting in some absurd 144p to 720p DLSS or whatever, or being CPU bound and cutting a lot of features. But how common will this be .. actually? Genuine question. And if a game misses the Switch 2, then there's no comparison to be made in the first place. Switch 2 will still be replete with excellent looking Switch games, PS4 ports, cross-gen games, indies, and so on so it's not like there's a shortage.
