- 4K mode, the big resolution and developers made the optimal choices



- 1080p high framerate, the game running at >45 FPS targeting 60



- 1080p bells and whistles, 30 FPS locked with every processing technique pushed to the max





That sounds good to me.





Edit :



The source was the Crystal Dynamic guy on the Sony live. I'm sure you guys can find it.



Edit 2 :



60 FPs target with dips, and over 45, so I assume 45 minimum, mentioned optimal for speedrunning though, where dips are death, so heh.



Edit 3 :



There is some confusion as to why it can run in 4K yet not hold 60 FPS at 1080P.



So I'm gonna add my 2cents, don't crucify me if there's a misconception, but this is what I gathered :



First of all, holding 60 is never an easy task, for any game using modern technology, at full HD or higher. When the action gets much heavier, when there's explosions, stuff falling etc... you can't control your game environment 100% in games with dynamic designs. So dips are to be expected, what really matters, is if the experience is smooth overall, and the dips not too frequent.



Second, the techniques they use to render at 4K are mostly GPU based. Sony focused entirely on boosting the GPU for ps4Pro.



The problem is that the CPu is garbage, so games that were designed to make heavy use of the Cpu can't magically offload the work onto the stronger GPu, that would require recoding the game.



How CD talked about their "high framerate" mode sounded rather convincing. We shall see.



What is sure, is that games conceived with neo's architecture in mind could dodge that issue, if they don't decide to only focus on 4K/HDR. (because 4K mode is never ever gonna run at 60 FPs)
