Hellblade 2 will be 30fps only on Xbox consoles

If you pushed so hard that you can't hit 60 fps then you need to pull back. It's not state of the art if it looks like a slideshow.

You have hellblade 2 already?

That the eye can only perceive 24 fps is a myth. Plus vision perception is very complicated with many different processes, and your eyes and brain don't strictly perceive things in frames per second. 24 fps is a relatively arbitrary number picked by the early movie industry, to make sure it would stay a good amount above 16 fps (below this you lose the persistence of motion illusion) without wasting too much more film, and is just a nice easily divisible number. The difference between higher frame rates is quite obvious. Just go grab any older pc game to make sure you can get a high frame rate, then cap it to not go higher to 24 after that, and the difference is night and day. Tons of people complaining about how much they hated the look of Hobbit movie with its 48 fps film can attest to this as well. You certainly do start to get some diminishing returns the higher fps you get though. Movies can be shot to deliberately avoid quick camera movements and other things that wouldn't do well at 24 fps, but video games don't always have that luxury. For an rpg or something sure 30 fps is probably fine. But fighting, action, racing, anything with a lot of movement or especially quick movements of the camera starts to feel pretty bad at 30 compared to 60.

Oh, sorry, I really misread it as Helldivers 2 :)
