Random Huge FPS Drops since 06/04/2019

[BrynXai]

This has started only at 06/04/2019, I'm not trying to speculate that it's the servers are fault or the game, I'm just laying out when it started.
Just recently my gameplay keeps getting interrupted with this drastic FPS drops from 140+ FPS to sometimes under 10 FPS which make the game unplayable at times.
The duration of this FPS drops vary from 2 mins to longer, or till I leave the zone, re-enter or use teleport.

Of course, I tried to troubleshoot this myself:
- Checked my drivers [ up to date ]
- Checked for background apps [ seems to be ok]
- Checked process for memory leaks, power consumptions. [ Everything is normal ]
- Checked my connection [ directly connected via ethernet, VPN says the game connection is between 44-60 ms ]

Initially, I thought it was lag or that it was a highly populated zone but I can be alone and Get FPS drops. So I'm thinking this is Instance issue?

I need to know if this is an issue on my end or maybe possible server side?
