Floor texture in Seabed looks funky

[Dan Maku]

I've started having an issue with the game: on the Seabed field, the floor textures look weird, like something is amiss with the lighting or something. It's not easy for me to describe, but I've taken a screenshot of the issue. I've tried rebooting my computer and running a file check from the vanilla launcher, but to no avail. How can I fix this?

hmm have you tried performance with best appearance.

change the performance of your computer to run on best appearance.

I can't turn the graphics quality up any higher without the framerate dropping significantly. XP

I've just run into another issue. During a "Subdue Fang Banther" EQ, the river appeared to be way too high: it looked like the surface of the water was hovering a meter above my character.
