As desperate as I am for this to drop, wouldn't it create probs on PvP. Would there be an an advantage for 60fps vs 30 fps? Or would the maths make it non-issue?
PC Dark Souls 3 certainly runs with a variable framerate AFAIK without that much trouble in the online mode. The same is true with most online games where the server-side stuff can run at a fixed rate while the client side runs as well as the hardware can deliver.
4K Bloodborne might not happen though consider even a really beefy PC GPU can't do it in DS3, at least at max detail. I would love something in between supersampled or checkerboard though.
