Exactly my concern. I do have a ps4 pro, I find 30fps unbearable so buy games that have 60fps options like The Last Of Us, GT Sport etc.
I'm hoping there is an option to run lower res 60fps in the options. If not, then I might just have to give it a miss.
To be honest, adjusting to 30fps doesn't take long. Yes it doesn't feel as 'smooth' but its certainly playable.
