While the latter could already be played in 4K, in many areas it was at 30 FPS. With the latest version, however, you can enjoy this resolution, but at 60 constant FPS, even in the most demanding kinematics or areas. Really a feat for the RPCS3 team. Its PlayStation 4 counterpart runs in 1080p at 30 FPS.
Meanwhile, ATLUS still does not recognize the PC as a relevant platform today. Hopefully a sample of how one of their games look like in 4K at 60 FPS will make them reconsider once and for all. Not long ago, ATLUS filed copyright strike against the RPCS3 development team to remove Persona 5 content from its site. According to a statement from RPCS3, this was done with advisement from Patreon, who did not immediately comply with Atlus’ request to take down the project’s page.
