This is a short article, but a quick note on why some games that appear to require a lot of power (such as the latest versions of Doom and Wolfenstein) have been ported over to the Switch, despite its lack of power compared to the PS4 and Xbox One:
The Switch may be under-powered, but it is not under-featured. It actually has all of the graphical features of the other consoles, it’s all just scaled back because of the Tegra chip it is using. Because of this, most ports are able to just scale back on the detail level, draw distance, texture quality, etc to run on the system. No game running on current-gen consoles actually has to undergo major changes to the rendering code to accommodate the Switch.
