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.
I dunno, I remember way back in StarCraft the original, everyone upon entering a game would immediately change their setting sto Very High Latency…because who the fuck knows why.
