for you face light haters out there, you can turn off attached particles and lights. Bling and lights go away, and, at that point, they don't create as much lag as the prim clutter you are wearing yourself.
Bling has been noxious for some time, long ago leaving the tasteful and interesting behind, and reveling in the ugly. Face lights are generally badly made, but not all of them.
If you don't know how to turn them off, don't be rude to those of us who do.
There is a sim in particular that I'm going to avoid, precisely because the local ignorati have started a crusade about this, not realizing that other things, such as color changing titlers, are much worse.
