The amount of loading screens in this game is kind of absurd.

[Felis]

The system needs to load for the surroundings or w/e computer term you want to apply, hence the loading.

Heck even RO with 2D graphics loads everytime there's a portal inbetween zones.

The graphic is 3D. Only the characters, NPCs and enemies are 2D

Here, I found this
Aurun Vale 1.0, no PS3 version, 4 zones





Or the old Cutter's Cry
