Developer doesn't think the differences will be gamebreaking
The "Xbox 720p" debate rages on, as CD Projekt co-founder Marcin Iwinski weighs in on the potential differences between the Xbox One and the PS4 versions of Witcher 3. Speaking to Eurogamer, Iwinski notes, "We are still working on squeezing the juice out of the consoles and Microsoft are supporting us in this respect. The final effect, whether it's 720p, 1080p - we had the debate in the studio about it and actually asked our tech guys to explain how it works, and they sent me some complicated graphs that if I have this size of the screen, and I sit one meter or two meters from it, then I might be able to see the difference."
Iwinski goes on to state that" it's more of a PR differentiation, which is very important for Sony right now - and they are using it, obviously - than something that is really meaningful to gamers." This pretty much gels with all of my Xbox One and PS4 comparison tests. Although it's clear that the PS4 has the edge most of the time with a higher resolution, it's never enough for me to think that I wasted my money on the Xbox One version. Of course, graphics wars have been around for decades, so nothing is really new.
