According to a report by pixel wizards Digital Foundry, Elder Scrolls V: Skyrim – Special Edition performs worse on the PlayStation 4 than it does on the standard PS4.
The report states that while the PS4 Pro version of the acclaimed fantasy-RPG hits 30fps “by and large,” there are occasions where it actually drops below the standard PS4 edition due to the 4K resolution.
Skyrim Special Edition PS4 Pro has performance issues
"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," the report says. "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."
Digital Foundry goes on to note that the game’s performance is not likely to improve when using a 1080p TV either, in which case the PS4 Pro version supersamples the naive 4K resolution down to 1080p.
"As such, the experience doesn’t feel quite as smooth when running at 4K, with more substantial hitches when moving through detailed environments," the report continues. "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."
Despite the frame rate hiccups, Skyrim Special Edition on PS4 Pro can be “ever-so-slightly better-looking” than the regular version, due to improved image quality and enhanced foliage draw distance.
