func_viscluster is an internal point entity present in all games since all Source games. Its purpose is reducing the amount of time spent compiling by telling VVIS that all the visleaves in the volume can see each other. Poor use will result in decreased performance ingame.

Note: In most games, the portal file will show that visleaves have been merged together, however console commands such as mat_leafvis 1 say otherwise.

Avoid placing a func_viscluster through the surface of a water brush or touching areaportals as both tend to cause visual bugs and leaks.
