FPS halved on ONE character only

[Goat7]

Hey all.
Just trying to trouble shoot an interesting, possibly unique, and very frustrating issue.
One of my alts on wow is having a frame rate issue. All of my other characters are fine.
I typically play at 1440p with all settings on max and enjoy 100+ fps all the time.

However, when I log on my mage, FPS drops to the 50-60s. To test things, I disabled all my mods,
ran a scan/repair tool on the launcher, stood all my alts in the exact same area and logged them all on.
Every single character hits 130-140fps, except for the mage. I even tried changing transmog. I've triple
checked video settings across my alts, everything is identical. Also tried updating to the latest Nvidia drivers.
Out of frustration, I swapped out video cards too. Still having the issue that is only on the mage...

Any suggestions would be greatly appreciated. I can't seem to find much info about frame drops on only one character.

PC Specs.
8700k @ 5.1ghz
16gb DDR3200 14-14-14-34-1T
Samsung 980 1tb x 2
Nvidia 3090 FE

All drivers up-to-date

nobody else is gonna point out he is running a 3090 with 16gb of ram? the video card has more mem then the PC...

has nothing to do with the issue but umm bro.... wtf

Hah, yea, only idiot would have bought that 3090 anyway, so overpriced.

Disable all of your addons on that character and see if the issue persists. If it doesn't, then re-enable them one by one until it returns. Very high chances this process will identify your issue.

It can also happen if you don't repair!

Disable MSI Afterburner OSD if you have it.

Also, this happened to me while doing revendreth chapters and I think it was between chapter 3 and 4 that my fps was cut in half like in your case and as soon as I finished said chapters the game came back to its senses. All other toons were behaving normal during that time 100+ fps at 1440p with 3080 etc.

Its game related and specifically quest related certain quests are just broken.

Edit: Please note that deleting WTF/cache etc DID NOT HELP. I had to endure this crap until I finished my chapter in revendreth and then suddenly everything came back to normal. Im petrified that I might go through this again for alts now.

Deleting all addons also didn't help. The culprits are two:

MSI Afterburner OSD (Running MSI AB in the background is fine)
Quest chapters in Revendreth (that was for me but other covenants could have similar issues).

Even rolled back and forth NVIDIA drivers with no change. Finishing the chapter was the only thing that helped.

Wow that's crazy because now that you mention it, I do recall a time I had horribly bad lag on my priest who is Venthyr.
