I have a issue with ping in sostronk its goes up and down inbetween the games and suddenly goes down to normal so help on this issue.
If the pings for other players in the server are stable, then it's an issue with your own ISP.
But before it was fine with same ISP and this happening after update.So how do i tackle this situation?
If you're talking about SoStronk app update, that doesn't make any difference you your network setup and your ping. If you're talking about CS:GO update, that affecting your ping is also unlikely but we can't be sure.
