It's hard to take Digital Foundry seriously when they keep repeating that the Switch 2 is roughly just on par with the PS4 with a big caveat and asterisk. Back in 2024 they didn't buy the concept that the Switch 2 is more powerful than the Steam Deck.
Games like Phantom Liberty, Split Fiction, Wild Hearts, and SW Outlaws aren't available on PS4 because of technical reasons but are running on Switch 2. In pure rasterization alone, Switch 2 is already above PS4 without adding features like DLSS, but how is it possible to run on Steam Deck, a system that's weaker than PS4?
SW Outlaws and Wild Hearts are unplayable on Steam Deck, while Phantom Liberty and Split Fiction needed to upscale from internal resolution ~400p to make them playable; that resulted in a pixelated and blurry IQ on the screen.

Switch 2 is running at a higher resolution (1080p) than PS4 (~900p) and with a better performance mode at 40 fps, while the PS4 version is dipping a lot at sub ~30 fps.

For the Steam Deck comparison, let this picture speak for me.
