Some Switch pics have zoom in from the handheld mode, so this comparison is just to have some ideas from the switch port nothing concrete.

Nothing you can really use to judge since it is zoomed. I guess we can assume that the Switch version is visually fairly close to the X1S version. We'll know the full story soon enough and I doubt the result will surprise anyone.

Are those screens from docked or undocked version?

This game is a great way to measure AAA games performance on the Switch. I hope this port become a success.

some docked and some undocked with zoom in.

0-29 sec doesnt look like its switch.
30+ sec looks like its gameplay from switch.

However Im hestitant to believe this, without him haveing access to raw footage from both systems like say Digital foundry does.

The Xbox is clearly superior.

The image looks soft on the Switch likely attributed to it's sub-par resolution.
It's lighting, shadowing and texturing also seems to be a step down.

Still. Wait on the Digital Foundry.

You are aware these are taken from a compressed YouTube trailer vs direct feed gameplay and most are 200x zoomed in?  The resolution and even texture and shadow detail can't be judged for crap with this.

The general lighting and rendering sorta can, and jt is in line with the Special Edition.

Stevie Wonder could tell you the xbox version is superior. Doesn't mean the Switch version looks bad

The xbox one version looks old and dated.

The switch version looks old, dated and blurry.
