Maybe you dont have an eye for these type of things? And theres nothing wrong with that, just enjoy it
I notice everything from better textures, further draw distance/improved popin, higher quality shaders, improved poly count, animations in things like flags and wheels.. higher resolution godrays, shadow quality, reflection resolution and type of reflection.. to things like grass quantity lol.
I notice it all.
As someone that loves all the graphical mumbojumbo, i notice the smallest of changes.
You could call it a side interest to games, i love the technology behind it.
And i think you meant PS4/PS4 pro 😁
