Much less taxing than full nameplates, try maxing the draw distance in InfoPlates and lowering it in your nameplates addon. This makes identifying an enemy's class in PvP much easier, without being as harsh on your framerate.
Type /ip for basic configuration options.
Can I change the vertical or horizontal position of the icon?
This will be configurable in the relatively near future.
Can I show only Prime NPCs?
Yes, as of version 1.1.
- Icon is drawn too high/low on mounted players, such as on top of/behind the nameplates of Chuas riding hoverboards.
