The only one I remember seeing is the Orange Packet loss, and that was only a couple of times, maybe a couple of months ago, relative to one of their patches no doubt, don't remember.
Packet loss would refer to the Internet connection, I have 24 hops, so it has nothing to do with my computer. Plus their game net code could cause packet loss.
If you look at my specs I cannot imagine that I have any weak components, other than my trigger finger.
I know other players have seen some of those icons as well. Those displays seem to come and go, they are not constant.
Knowing how DICE codes I doubt that they are even accurate.
I have spent a little time on a couple of other servers and experienced no problems.
So maybe it's the number of hops, or the line coming from the server that gets hit real hard.
I know others have used the terms; lag, jitter, hesitation, rubber banding, stutter, and so on.
For these symptoms being intermittent, to me, proves that it is not my computer, but is due to other conditions.
What we could do is have a test night, couple of hours, where we could be the only ones on the server and set it to 120 htz with no high pingers.
I would be interesting to see if anyone sees any of those icons.
Anyway I thought some people would be interested in what the icons are supposed to mean. Oh well, DICE makes for a great conversation.
