Only happens when you aren't moving very fast and possibly when you aren't zooming.
Actually, it does happen when I zoom and sprint... :/
Seems like this feature (if it even is a feature) only half works. Doesn't seem like everyone sees it. Tbh it seems like an odd glitch rather than something they put in the game.
What resolution/FOV do you play it on?
never ever seen either
1920x1080
I've never noticed those indicators, but since I'm running 5760 x 1200, I don't really notice much on the edges of my view unless I actually turn my head to look.
Agreed with OP.
I play on a 1280*1024 screen and they are very obvious. Besides also showing friendlies, it would be nice if it also showed false positives and false negatives from time to time. It should not be something you can rely on for 100%.
Ironically, PV indicators sit just outside of the central cone of detail for the typical human eye looking at widescreens (22-24"+), i.e., they aren't easy to notice. If they are going to stay in they need to be fair for all players wherever possible and that means making them larger and rapidly flash black & white so human peripheral vision can detect them. This probably means making them quite annoying; annoying = good as far as human PV detection is concerned.
