that's bad
This console is something completely different. It's basically the next generation of Nintendo's handhelds with the ability to output to TV. People keep thinking of it like a standard console that goes portable, but it's completely the other way around.
In order to prevent the power draw from being RIDICULOUS and the heat output from being loving HOT and the weight from being a TONNE, concessions in the physical hardware have to be made, just the same as how laptops work. Naturally, this means intensive games are going to have to receive cutbacks when you try and push them beyond what the hardware was designed to naturally do.
If you want the full render, go for the Wii U's increased-fog, decreased-details edition (which would otherwise also need to run at 900p if it attempted to have the same fidelity at the Switch Edition). Nintendo is notorious for efficiency and squeezing whatever they can out of the smallest amount possible, so you just know that this is the best that anybody could achieve on brand new hardware.
Just remember that the Switch itself is a 720p device with a 6.5" screen that needs to be able to run 60FPS intensive-3D worlds on battery. Point to me any currently existing mobile device that can do that well (I know for a fact that not a single iPad has that capability as my app failed to certify due to the low memory of the devices).
