There are 2 traces. This can not be changed because otherwise some headshots would not get detected. This happens because the trace can end in the bounding box which fully contains the head box, or at least blocks it. The extra leg box is added only for one player if it hits his bounding box. Not for every player or if the hit is already in the head. The behaviour is the same regardless of the g_realbody setting. I.e. if g_realbody is used, the leg box is not added to every player. This same double trace and additional entities is necessary for all hitbox systems. Do note that we have already removed many redundant traces that are present in the etmain or in the ETPub for example. The information of the hit, once resolved, is kept as long as it is needed. The additional overhead from adding one extra leg box to one player is not mentionable enough. Furthermore, it is combined with the fact that the total count of the traces (and building bodies) is already reduced. There migh be some options to improve the performance slightly. But you shouldn't think it would reduce server CPU usage significantly, even with lot of hits to the players. It must be removed from it. Thanks.
