I can only tell frame rate if I focus on a single object. If I focus on a million pixels at once I don't see it.
The human eye and brain is not designed to be so attentive. High frame rates actually caused motion sickness in its heyday with those Sony Bravia 200fps TVs they used to sell. The brain doesn't enjoy seeing things move too quickly, it won't even notice on a conscious level. Subconsciously you may just feel a bit sick.
You just have an inferiority small penis complex where you think the more/ the higher the better.
Doesn't work that way, analyse it objectively and think for yourselves.
4k has the same cognitive bias, albeit to a lesser extent. The benefits of 4k are there but not that much more so than 1080p.
The human eye is not advanced as you think. It evolved to evade ferocious lions on the savannah of Africa, not judge the number of frames over a millisecond.
The game design itself is the most important thing, good lighting, detailed textures, realistic shine off images etc are much more important.
These are things the eye actually notices
