I don't know if this is a problem or lack of understanding of the new update, but here yah go.

Cannot see players on radar past 500M. Is this working as intended or ? If ?, what would be the proper setting for 5000M.....

In the past I had typed this...  /radar .5 5000   and could see across the map NP... did /radar f to refresh

enable Draw Distance Players With X if you want to see the X only, or set Drawing Distances for Players to a higher value such as 5000 if you want to see the names instead.
