Currently most games are devoloped to be 1080p 30fps for PS4 as a priority. But with the PS4 Pro you could make just the PS4 Pro version 1080p or above.

Developers should focus more on 900p and 60fps for normal PS4s and make it 60fps 1080p or above on PS4 Pro. Nier Automata is a good example recently or Battlefield 1 running in 1440p 60fps. Opinions? 

I've got a ps4 and xbox one and a 4k tv and while I can see the ps4 is often sharper I don't care that much about the difference. I'm fairly close to the tv too and its 49" which while not huge is a reasonable size at least here in the uk. I'd probably like the option on ps4 to render at 900p just to make the 30fps frame rate more rock solid. To get to 60fps will need some sacrifices in graphic detail and I think has been shown consumers are enticed by great graphics.

I love the feel of 60fps gaming though but with modern tv's with their input lag it just doesn't feel the same as playing 60fps games on a CRT tv which were super smooth. My tv has a reasonable input lag of 31ms and the best can be as low as 21 and the worst over 100ms but CRT tv's had 0ms lag unless they were premium models with 100/120hz output or high res tubes with upscaling.

Stable framerate should be the priority. Some games can run at 60 fps but it's difficult for some games even at 900p, like the witcher 3 or fallout 4. Those games on the normal ps4 should run at stable 30 fps and 900p instead of 1080p with framerate dips. So it depends, but stability should be the base line, these are consoles an you can't expect every game at 60 fps, even on the scorpio or pro. 30 or 60, stable framerate that's the best option imho.

Yes. 60 frames should be standard. Some games get away with 30 however those are normally visual only games like Ryse and The Order.
Any game where you have to aim should be 60 flat. Its just a much better experience. Its not like 900p or even 720p isnt sharp. Its still HD. If they made them below 720p ill be worried.

Why cant the Standard be 1080p 60fps on regular PS4 and higher resolution on Pro?

Sure or they could give options on Both Ps4 of and Pro.
With one Having 1080p/900p 30fps with "higher graphics"
And other Version 1080p/900p 60fps "lower graphics"
So anyone can get the thing they want if they want Fps you get let's say Fps mode with 60 fps lower graphics or Graphics mode better graphics 30fps.

Like with NI Oh that game has a lot of Options to chose how you want to play.

I think that as the generation rolls on the base for PS4 and XBO should drop. I would be fine with games being 720p/30fps - 1080p/60fps on the base PS4/XBO, PS4 Pro & Scorpio being 1080p/30fps - 1440p/60fps, and a new Spec 3 PS4/XBO being 1440p/30fps - 4K/60fps in 2019 or 2020.

I feel like there is a wide enough range of console gamers that these diferent markets are justified. Some people are happy with their 720p or 1080p screen, and they still will be in 2020. For those people a $100 PS4/XBO without a disk drive and 512GB of on board RAM in 2020 would be the device they are looking for. For others a $250 PS4 Pro or Scorpio Slim would be perfect for there 1080p or 4K screen. The final group of early adopters, gamers, and tech enthusiasts would be happy with a $500 PS4/XBO Spec 3 that delivers full 4K and up to 60fps.

This is the way I think the market is heading. I feel Microsoft is absolutly heading in this direction, and I think even if Sony decideds to make the PS5 in 2020, the PS4 and PS4 Pro will still recieve the newest titles from Naughty Dog, Sucker Punch, Polyphony Digital, and the rest of SIEWWS for quite some time. The days of completely dropping 100M people in the transition to the next generation are over, and the the days of limited or no backwards compatability are over.

Tag.

Standard PS4 is not powerful enough to push 1080p60 with the usual targetted details.

I don't think base PS4 is powerful enough to do 900p60 across most titles. Not without significantly lowering game detail to a point of blandness.

720p60 would be possible.

IMO Sony should have made standards since the beginning.

Base PS4: 720p60; 1080p30

PS4 Pro: 1080p60; 1440pC30;
