If you own a Magic HUD from any SL builder, please remove it BEFORE coming here. Those HUD throw several LAGGY prims that stick around your body even if you simply wear the HUD, and not use it. The lag that they cause is AWFUL.
Sorry.
ps: on the bright side, the new SGS v 3.0 is going to have magic spells etc. low-lag, and no prims, since it is all embedded in the system.
