If you've been wondering how the Switch's iteration of DOOM holds up, here's a direct comparison for you.
Spanish YouTuber ElAnalistaDeBits has taken a bunch of DOOM footage from the PC, PS4 and Xbox One and compared it with the Switch version, which is due out tomorrow.
In general, the difference between the versions is what you'd expect. The PC has the clearest and sharpest detail compared to the consoles - it's running on a GTX 1080, so it should - whereas the Switch port is much blurrier, has less effects, harsher shadows, and less detail in general.
That said, it's a pretty impressive effort nonetheless! If you want to get a clear indication of some of what's missing, have a look at the gun model. Here's the PC version:
And on the Switch:
There's obvious differences, and the closer up you zoom and the more you look, the more downgrades you'll find. But overall - and for something you'd be probably playing in handheld mode - it's not a bad effort.
You can see the full comparison below. There's no action sequences, unfortunately, so there's no ability to see how much dynamic scaling might be present on the Switch when enemies are on screen or something like that. But it'll give you an idea of what to expect, which helps.
