Quality per pixel is a debate that is game dependant. The idea that esram is a limiter to resolution is not correct. There has been significant evidence to show that esram can be worked with if the developers goal is to release a 1080p frame buffer for their title.So, Fifa 18 is more optimized than W2 because it runs at 1080 on XB1 ?
And you have to lower the resolution if you want the same result than on PS4. It's completely trivial... there's nothing specific with Esram.
