A new comparison video created by Digital Foundry compares gameplay footage from the PlayStation 4 and the Xbox One version of The Witcher 3: Wild Hunt, taking at look at how much patch 1.03 actually helps with frame-rate issues.
Unfortunately for the PS4, gameplay footage from the video indicates that there are still a lot of frame-rate problems, especially in swampy, wet areas. There are some issues on the Xbox One version too, but when shown side-by-side, it is clear that the PS4 version is quite a bit laggier.
Hopefully, the upcoming 1.04 patch will fix some of these frame-rate issues when it releases. Have you noticed any frame-rate problems on your version of The Witcher 3: Wild Hunt? Do you think patch 1.03 helped at all?
