Massive FPS drops and sound distortion since pre-patch

Hello everyone, after the pre-patch installation I have encountered a weird problem. I will try to describe it as good as I can: upon entering the game all of my sounds are distorted, delayed & no sound at all (Abilities, bags opening, world sounds etc.) and after a while I get a massive FPS drop (From 60 to 0 and game freezes for a few seconds) and the delayed or missing sounds, dialogues etc. are played all at once. Before the pre-patch I had 0 issues with the game, high stable fps, good sound quality. THIS PROBLEM OCCURS ONLY IN WORLD OF WARCRAFT. I had no problem running any AAA games at high settings

  • Updated all of my drivers (GPU, Sound Drivers and even Windows updates (??)).
  • Completely removed all of my Addons
  • Re-Installed the game
  • Uninstalled Beta
  • CPU and GPU Temps are completely fine. 45 - 65 °C & 50 - 60 °C
  • Tried adjusting the sound options in-game

Unfortunately got no result. I am desperate

Hardware specs:
Win 10 x64

  • Ryzen 5 3600
  • RTX 2060 MSI Gaming Z
  • 16 GB DDR 4 - 3000
  • 1 TB Samsung SSD
  • 500W be quite pure power 11 (I really doubt this is the issue)

Thanks in advance for the help.

Aside of WoW bug you could check for Nvidia - Audio drivers conflict. Run “latencymon”, run wow, make it drop FPS, alt-tab to latencymon and check if it’s all red. Then DDU Nvidia driver, update audio/board drivers and then reinstall Nvidia drivers.

Update: Disabled wow sounds and that fixed the issue (No more fps drops) But that’s not a real solution tbh.
