Here's how to remove the non-functional sea plants and sea bed rocks eyecandy:

Just move to different directory or delete the Undersea.dat file located in your SH4 data/library folder. I have noticed higher framerates after they are removed. The seafloor will be sandy after removal. It just looks better in my opinion. Yes, the game will run smoother and still work as normal.

**Edit** Sorry about that.. it's the undersea.dat. file.
