These nebula (blue smears?) in the Borg encounter have caused me massive lag much like what was experienced in Mirror Universe before it was removed there. Why take a laggy element such as this and just move it from one place to another?

PLEASE REMOVE THEM!

Or at least give US the option to. My video card, for whatever reason, cannot handle them on any setting. Everything else it can, no problem, except these. I do not want them. Please allow us to remove them via video options!
