My monitor has it, i've never used it outside of "what does this do?"

And it had like, 6 different crosshairs.  dot, reticle, sniper crosshair, etc

Yep I have an ASUS with the same lineup I've used the green and red dot in Siege and Valorant

Valorant is funny though since spectators can view your crosshair and when using my monitor crosshair I disable the in-game one, a lot of "how/why tf are you playing with no crosshair" comments.
