Bloodborne still runs bad. It will be perfect game to release for PC. HZD...looks and plays well for most part. Nevermind the game.
Pro turned not so pro for people who just want to play exclusives on PS4. Maybe okay for multi-plats to some extent but I didn't see any major difference in exclusives to justify the price or upgrade.
The visual 4K bump brought down the framerate by half and it wasn't smooth. And if you went for performance boost, it is pretty on par with base/slim editions at 1080p.
