PlayStation 5 and Xbox Series X will be able to push next-gen titles beyond 60 frames per second, but some next-gen games have already been confirmed to run at 30 FPS. According to the PlayStation 5 former principal software engineer, there a few reasons behind this choice.

Speaking on his Twitter profile, PS5 former principal software engineer Matt Hargett recently discussed next-gen games running at 30 FPS. The choice is constrained not only by wanting the game to be "filmic" but also by the choice of pushing HDR and the TVs most people have. When the cheapest 4K TVs can only do 4:2:0 HDR at 4K, 60hz, 4:2:2 4K, 30hz will help more people experience it.
