You’re misinterpreting what was referred to as a ‘glitch’ to what the symptoms are in this case.
The ‘glitch’ you’re talking about is less smooth, while the zone layer is basically swapping places on the server’s allocated resources from one to another which has its own built-in delay as a consequence.
So you get the controlled setting rubberband effect, because the server temporarily stops sending you such information in those circumstances.
Also, that talk about the GPS coordinates, is affected by network effects and settings as well. Which is why the last sent information your machine received shows them doing the running man, which is then followed by the rubberband effect because the server starts sending the information again.
And yeah, due to the priority settings in the data flow which was changed on retail to accomodate for CRZ and everything else that followed, it means that most likely the larger servers suffers more visibly from this.
Since it is, as mentioned, related to the server’s capability to process the information as well as how it prioritizes certain things over others for a more stable “illusion” that it’s in real time.
I can accept that there will be a delay switching between servers but still disagree that that is the whole story
I have experienced huge ‘lag’ in retail on a world boss whilst other players have not - indeed - i have been seeing 1 frame every couple of seconds whilst they have been happily fighting the boss
If everybody was suffering all of the time I would agree this issue was with Blizz
But that isn’t the case
Humour me - lower your graphic settings and see what happens
