Will this add better framerate at 1080p or not?
I imagine not. Devs wont want to have a 4k version at 30fps and 1080p at 60fps
There's already one dev doing it.
- 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
