How do the visuals on the Nintendo Switch compare to those of the Xbox 360 & PS3?

[curl-6]

As impressive as they were for their time and hardware, PS3 graphics look nowhere near as good today as those arguing of favour of them claim.

In terms of textures, shaders, effects, etc they are clearly outdated compared what the Switch has shown itself capable of.

It's fair enough to prefer the art direction of these titles to Switch's top lookers, but when it comes to performance, the specs don't lie.
