I don't mind it being 30fps but not achieving 1080p is kinda disappointing. Phil did say that the new 10% reserve would be put into the effects and other things so maybe they opted for that route rather than upping the resolution.
10% wouldn't get you anywhere near 1080p from 900p though, and it wouldn't solve the limited esram. Better to aim for a resolution best balanced for that (eg 900p) and use any extra power for effects or framerate stability
The game looks incredible. So vibrant. Wonder though, with the One struggling for 1080p a lot so early on, as the gen goes on will they push for more visual effects and continue to struggle or will they get their heads around the hardware better and resolution/frame rate etc will improve?
Both Ps4 and Xbox 1 will be under increasing pressure on graphics quality as PCs get even more powerful. So I expect more Ps4 games to potentially start being 900p, and xb1 possibly lower.
