People might claim not to have that problem, but they're either not noticing it or lying.
I don't have that issue, and my rig is not state of the art anymore (though it's still rather solid). I've seen tons of complaints though, without any specific pattern in terms of hardware.
Anyway, when I refer to PvP I mean it boils down to Warzones = Battlegrounds. There are PvP related activities in both games beyond the Warzones/BGs, but very little incentive to do it.
