Motion handling varies a lot by TV. You can't make blanket statements that 60Hz TVs won't be smooth, it depends on the technology, the picture mode and different options the user may have selected (although if you're not using Game mode you're being silly - input lag!).
I played it on my PS4 Pro on an LG B7, no complaints. Maybe I'll run it on my PC with a CRT monitor, then we can all marvel at how smooth it is.
What's more interesting is seeing first party Sony games coming to PC. Are they going to move more multi-platform in the future?
I imagine the earlier games would take longer to remaster to an acceptable level on PC, maybe they will come later? I have the uncharted collection and I can highly recommend it on PS4.
Either way, I hope this is an early indication we'll get Gran Turismo on PC. How about that for a off-topic twist.
