So, I am playing this on PS4 Pro and TMK the resolution is a native 4K.
It looks great, but DAMN is it stuttering like crazy and feels janky.
I dunno, maybe they should drop the resolution a tad because so far I am not impressed with the performance.
Yeah, and it's not just you. -- quotes from Digital Foundry:
Skyrim on PS4 Pro runs at native 4K - but there's a catch
The standard PS4 version has smoother performance overall
Sony emphasizes that games running on PS4 Pro must have frame-rates that are better than or equal to the game running on the standard PS4 console. However, that's not the case with Skyrim, where the increase in resolution can lead to a visible drop in performance in scenes where the GPU is pushed more heavily.
For example, scenes that feature use of alpha-heavy effects cause frame-rates to deviate from the desired 30fps target. In like-for-like situations, the PS4 Pro game sees a 2-3fps deficit, resulting in more noticeable stutter compared to the title running on the standard PS4 console. The base PS4 performance isn't impacted to the same degree, with only a few 1-3fps drops cropping up on occasion across a general run of play.
As such, the experience doesn't feel quite as smooth when running at 4K, with more substantial hitches when moving through detailed environments. It's not a deal-breaker and by and large, the 30fps performance target is met. However, the drop in frame-rates does feel like step down from the more consistent 30fps update present across the standard PS4 and Xbox One consoles running the game, and that's a shame as the jump to 4K really does provide a tangible upgrade in visual quality in other areas.
at least in terms of resolution, as frame-rates remain capped at 30fps. However, performance isn't as solid as the base PS4 game, and ultimately we have a trade off in smoothness for an increase in raw image quality.

So, while Skyrim Special Edition has a good stab at bringing the native 4K experience to consoles, the execution isn't quite flawless and it's actually Pro users with 1080p screens that get a raw deal - they get the exact same performance as the 4K users owing to the super-sampling implementation. The end result is that while it may only affects the game in certain scenarios, the bottom line is that Skyrim runs smoother on base PS4 hardware than it does on the Pro - and that's just not good enough.
