It’s always been useful in figuring out if you need to lead or trail a target more in a shooter, but all these modern shooters have taken that bit out of the scoreboard.
Checking out The Finals and for the first few games, I thought it used projectiles for the guns because I hit more often shooting ahead of moving targets, only to find they are indeed hitscan and hit better when actually looking directly at the dude when nobody is lagging.
There’s still a way to do it but it’s convoluted compared to if they’d just add a damn resource monitor into the game itself.
If you still care about figuring out your ping: this comment on reddit from a year ago tells you how to find your games server IP, from there you can just fire up command prompt and hit with
ping -n 100 <IP/Adress>
This should return your ping and packet loss with the server.
