Something DF didn't touch on. There are some obvious texture quality differences at times. I noticed them watching in 1440p, so I upped it to 4k, and I could see them in motion. Obviously you have to stick to moments where the lighting seems to cast the same on the models, but in my first example, on the left here, there is an obvious (if you're doing a tech/magnifying technical look at it...level obvious..lol) texture resolution difference.
The texture resolution isn't even close if we're being picky. Granted, it's like Ultra vs Very High...lol. It doesn't appear to be a dynamic resolution situation at all.
Seems like that would be hard to miss with how closely things are looked at.
