Finds entities inside a sphere with the given radius. If the alternative syntax is used, only entities of given types or subtypes are listed. Entities returned are not sorted by distance. This command doesn't return dead entities or entities inside vehicles. If you need to return those, use [[entities]] command.<br><br>

This kind of functions remains FPS killer if you can't manage conditions in order to reduce operations for each entity or, to reduce the number of entities.
One of the most demanding CPU/GPU resource is probably a DrawIcon3D treatment for these entities.
Don't stay with a simple radius condition (disk selecting entities).
Each time you can treat visible entities, as icons displaying, try to restrict this function to your screen.
For example: 
if (((worldToScreen (visiblePosition _x)) select 0 > (0 * safezoneW + safezoneX)) &&
((worldToScreen (visiblePosition _x)) select 0 <(1 * safezoneW + safezoneX))) then {...} foreach _pos nearEntities _radius
