I don't think its just the res/fps being turned down and thats got people a little annoyed. Its just yet another downgrade in someway. It was the delay, then the downgrade from the reveal, and now we learn it can't even do it at 1080p.
That and we're just noticing inFamous beats its vastly in terms of graphics, yet can still handle 1080p. That is what I've been fearing though, I hope devs don't see all these "outcrys" over resolution and tone down their visual effects in order to reach 1080p specifically.
Maybe at this point of time though... I'd like to think PS4 can handle the visual effects and 1080p, (if not then I'd rather have the visual effects), maybe later on in its life I can understand if it can't handle the visual effects + 1080p.
Whats been standing out for me this gen so far (at least for PS4), is the material textures and particle effects. inFamous blew me away with visual effects, but I also noticed material textures have got to the point where I can...sorta predict how that material feels or what that material is exactly.
