Noticeable but there'a huge gap between between where NX/PS4 is and midrange pcs it's clear as day with multiplatform benchmarks in some games at 1080p, it's noticeable in GTA5 which is a last gen product. I'm literally saying it after that controller thread people wanting or thinking that we're getting some mega good cpu might want to tone it down.
I mention the SDK because by no means whether it's rumor or my source am I hearing this amazing shit this thread is implying either. If it's amazing then let one company pull off what factor 5 did with the GC games in terms of high tech being done in a few months. Otherwise for all intents and purposes it's hogwash. I don't care if you can port low end indie game, that's something the X1 can do. Let see this system handle something like witcher 3, which could utterly prove my point hypothetically.
