WoW with the RTX 2060 6gb

I just got back into wow and I played the Dazar Alor raid. My FPS spiked to way below 0 during the Opulence encounter (I thought the game was going to crash a few times) and around 20 on some of the trash… this was with my GTX 760 SC so I figured I need a new GPU as my 760 was about 5 years old and some other games were starting to lag too.

I upgraded to a new RTX 2060 6GB and the performance is the same or maybe even slightly worse…

I got pissed off and turned all my settings to 1 just to see what would happen and I’m still getting huge FPS drops. As low as 25-30 during trash in Dazar Alor.

My specs are
Intel core i7 4790k liquid cooled
16gb DDR3
RTX 2060 6GB DDR6
Samsung SSD

Anyone else having FPS problems? I ran every single thing including Tarren Mill vs Southshore, and all raids in Legion at absolute max settings. And I didn’t see lag one time the entire expansion.

Did you ever figure this out? I’m having similar issue.
