Upgrading graphics is basically just a matter of switching graphics rendering from a Ps3 to a Ps4, that's all.

Where it really changes is when people add shaders.

Take a look at Ghost of Tsushima or any other game that isn't an MMO, it's always graphically more beautiful.

What did you expect? The liveletters always seem to tell us how wonderful the graphical change is, but it's still below any game released on Ps4. Whether you like it or not, this is still a Playstation-based MMO, and we'll be switching to Ps5 graphics at the next opportunity.
