[FF7] Difference of the lighting in PSX and PC

[Kaldarasha]

I have currently checked two vids of FF7, because the lighting of the PC version is entirely different.
PSX https://www.youtube.com/watch?v=K-fwg4VQxwI
PC https://www.youtube.com/watch?v=Xl3H5pVeo4Q
As much I could see it, it seems that the PSX renders the light only once at the start of the scene on the model and on PC the light comes clearly from one direction and is updated every time when the model moves.

Can somebody confirm that I'm right?
