1440p>1080p On a per picel basis the amount of data resolved is fixed. So if you resolve for a 1080p image you will never see 1440p/1800p/2160p details automagically appearing. But if you resolve for a 1440p image, as is rumoured to be the case with U4 on the PS4pro, downsampling/supersampling from that to 1080p carries most of the detail rendered at that higher rez and makes them vissible on a 1080p set. It will still not be tbe same as running it natively or on a higher resolution display but thsts more to do with the screen door effect (think gaps beteeen pixels, more pixels you hsve the harddr those gaps are to spot) than anything else. The "resolution gain" you are seeing in these comparison shots is due to the reference image (game running on PS4pro@1440p instead of 1080p) having a higher pixel density (which means more details are resolved). On a 4k display, this would look even better than what you are looking at here. |
When you downsample a 1440 image to 1080, it losses all the high frequency information, so is basically the same thing as rendering at 1080p, in details. It is what maths from nyquist shannon sampling theorem tells.
The only advantage is on AA.
