it was fully capable of running RDR2, still one of the best looking games out there, at native 4K wasn't it?
it also ran Rise of the Tomb Raider at native 4k... or Forza, or Gears 4... some stunning looking games, all native 4K
so if you say it was a lie that the One X was capable of running games at native 4K you are intellectually dishonest..and not just any games, some of the best looking games of the last generation.
in fact, given the usual resolution divide between PS4 Pro and One X, which was usually a 2x in favour of the One X, we could very confidently say that the One X would most like be able to run The Last of Us 2 at native 4K
