For it to run at 60fps the developers From Software would need to do a little work to it. And also for it to be rendered at 4k native would require some retooling since it's got a locked resolution which is tied to frame rate. So a remaster would be welcomed since From Software would not be the people working on it. They are knee deep in Elden ring, and a new IP that supposedly is PS5 only. Possibly the game is set in same universe as bloodborne.
