World of Warcarft poor performance with Addons

Hello

I’m a new Lutris user and just installed World of Warcarft, the only game left that kept my Windows partition alive.
Installation worked flawlessly and the game runs great, I’ve got about 120fps and just made a warfront yesterday (30+ people zerg) and it didn’t drop below 50 wich is phantastic.
Sadly when I tried to install some addons the performance dropped drastically into an unplayable state. Did someone experience similar issues? Playing this game without any addons on a more competive level (mythic raiding, high m+) isn’t very pleasing.

Thanks and have a good day all.
