this is so wrong MS has had games that were 900p run at 4k with no problem
Yea, but we don't know how consistently that would be achievable. There are all sorts of reasons why a 900p game could be 4K on XB1X:
- The memory configuration is the issue (deferred rendering often caused this).
- Game runs at 40-50fps average on both PS4 and XB1, and is capped to 30fps.
- 1080p was a narrowly missed target, and 900p was settled on.
- Game needs 40% more performance to move from 900p to 1080p.
The last of these would be the most likely to not manage native 4K on XB1X, as it would imply the 1.8TF of the PS4 is what was necessary, leaving the requirement closer to the 8TF Cerny is quoted as being the target for native 4K (would you look at that! he picked something that would handle 4x the PS4... how strange!).
Here's the thing though. Even
if the XB1X were a 8TF console, it still wouldn't make sense to base it's 4K credentials on the PS4.. because it couldn't be verified. Multiplat games don't work, as they're not actually the same game despite all the similarities, and disparities aren't consistent to the hardware. A 1080p PS4 game may be a 1080p, 900p or 720p XB1 game... but a 1080p XB1 game is
always a 1080p XB1 game. And you don't have unanswerable questions like "could it run Horizon Zero Dawn at native 4K".
Would anyone subscribe to that stupidity, knowing the pro is the same mid gen refresh as the xox?
Base ps4 is from the same generation as the xb1, and inarguably the more widely adopted platform. A maximised 1080p ps4 game can't run at 4K on the xox. As such, it can't be considered by anyone (who is not limited to the xbone perspective) to be a true 4K machine.
Generation doesn't matter, that's the
most arbitrary measurement of all. The Wii sold 100m, so by that measure the 360 and PS3 would be
comfortably 1080p consoles. But they can never play Wii software, and the XB1X can never play PS4 software, so its irrelevant.
Obviously very few people would bring something as ridiculous as the PS4 Pro up when talking about the XB1X rendering at 4K, but if you're going to start throwing "regardless of brand" in, then you could similarly throw in "regardless of generation" also. Ports aren't all made equal, and so they would be a meaningless metric. Running
the same software isn't on the other hand.
