Resonance of Fate 4K/HD Edition: Details on the Upcoming Remaster - PlayStation Blog
"This was a challenging project for us since not only did we remaster it as an HD version, but we fully committed to taking it to 4K resolution. In order to make the pre-rendered movies 4K, we had to utilize ‘deep learning’ our proprietary technology in order to up-rez. We also strived to maintain 60 frames per second at 4K resolution."
"We also fixed made sure to fix some old bugs and improved the load times to make for a better game playing experience. It’s a remaster that still has over 100 hours of gameplay with a dynamic engaging battle system that we hope you’ll enjoy. We’ve enjoyed remastering a game that allows players to have their own play style, customization and ingenuity to get through the game."
