Major Performance issues (certain areas only) PC/Win10

[theinsaneeraser]

I am having this same issues, mostly in 24 man content. when I do trials, it's fine and at the start of alliance raids/delibrum, it's fine, but it will very quickly start stuttering, like I'm only getting 1-2fps [very stuttery, aoe's popping off right as they show up, taking a while to register me using abilities, movement not showing, only sliding], but when I open system config to see my frames, I'm still showing as normal amount of frames [for me between 13-18 fps is normal] exiting the game and re opening fixes it for a short time, but it doesn't take long for the issue to come back.

I have ALSO noticed, that even though I have party effects OFF I can when this happens, see party effects, like red mages verfire and verstone going off on the boss.

I tried resetting my router, my driver's are updated, I restarted my cpu many times, and let my cpu stay off over night. This has only recently started happening. I do have a low specs cpu, but I've been playing this without much issue for a few months now.

Ah, I should add I'm on the NA Aether Data center, playing on faerie.
