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

Description

Description:
sphere radius.jpg
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.
ⓘ
This command is much faster than nearestObjects for on-foot soldier and vehicle detection.
Groups:
Object Detection

Syntax

Syntax:
position nearEntities radius
Parameters:
position: Object or Array in format PositionAGL or Position2D - center of the sphere
radius: Number - radius of the sphere
Return Value:
Array of Objects - not sorted

Alternative Syntax

Syntax:
position nearEntities [type, radius]
Parameters:
position: Object or Array in format PositionAGL or Position2D - center of the sphere
type: String or Array of Strings - type(s) to search for
radius: Number - radius of the sphere
Return Value:
Array of Objects - not sorted

Examples

Example 1:
_list = player nearEntities 20; _list = ASLToAGL getPosASL player nearEntities 50; _list = player nearEntities ["Man", 1000]; _list = ASLToAGL getPosASL player nearEntities ["LaserTarget", 3000]; _list = player nearEntities [["Car", "Motorcycle", "Tank"], 50]; _list = ASLToAGL getPosASL player nearEntities [["Man", "Air", "Car", "Motorcycle", "Tank"], 200];
