Severe Lag Spikes (Only on Certain Characters)

I’ve been having recurring issues with lag, specifically with high MS as shown in the in-game graph. Every 2 seconds my ping spikes from 11 to over 200, and this happens on any map, in any instance, and even when switching servers—for example, from São Paulo to Washington. The lag and problems remain, and it gets even stranger because the issue only happens on certain characters.

For example, I have one character that I can play with 0 lag and no problems, even on the exact same maps where my other characters experience constant lag. Nothing happens with this character—he’s the only one I can actually play. But if I create a new character, whether on the same server or on a different one, the issue comes back. The only character unaffected is the very first one I created this season.

I tried coming back to the game, but it’s currently unplayable. I understand it’s still in early access, but I see many players—including people in the same region/state as me, using both the same and different ISPs—who have no issues at all. I’ve already tried everything I could find online, even tweaking 3D cache settings (which seemed to help others), changing DNS, and other fixes, but nothing works. I really just want to be able to play the game that I paid for.
