I think there's a difference between "30hz" as in, the refresh-rate and a game locked at 30fps on a 60hz screen.
I would never run my desktop at 30hz, but I am currently playing God of War on PS4 Pro and it looks great and runs at 30fps, which is perfectly playable.
Is 60fps better? Absolutely no question.
Is a locked 30fps unplayable? Not at all.
Its a very good game yes. I too have completed it on the ps4 pro and while it does look and play well at 30hz. There's always the what if. What if the pro was better and could actually run the game at 60hz. What if this was available on pc so i could play this at 60hz.
I can switch any game from locked 60hz 4k to locked 30hz 4k and the difference is pretty apparent. I'm not saying its unplayable because it isnt. But given the choice, 60hz is far superior.
