60 fps in most games would be a dream come true on consoles. I am sure though that the users of 1080p displays are in luck and will run their games at 60 fps on Scorpio.Sure 30fps will be the norm on Scorpio because most Xbox One games run @ 30. Now if a developer builds their game from the start with 60 fps in mind (Ex BF1, Forza,Halo5) the Scorpio will handle 60 fps with ease. They built the Scorpio to run most Xbox One titles that hit 1080/900p at full 4k regardless of the titles frame rate. Also the comparison of the Scorpio to the power of the 980ti isn't really valid. They have completely different architecture for one and consoles always punch well above their weight compared to PC parts.
It is that aspect that I think matters to most. Internet speeds, Game mode on our TV's, Ping etc etc can create either advantages or disadvantages. It is going to be a good source of analysis seeing how games featuring unlocked frame rates on the XB1 games compare to the Scorpio version.
Not sure of many multiplayer games running closer to 30fps rather than to 60fps but it is entirely possible we will see a bigger difference than Battlefield 1 on PS4 Pro and PS4. The game isn't so much different but alas I think more people would be vocal and upset if future games were capped at several levels even if this means a smoother experiencing for Xbox One users.
