Why is it under graphics card it’s saying that it’s running graphics card on low power? Anyone know how and if I can fix that?
is your card supported via this supported card list?
have you actually clean the card, checked the wiring etc. Updating the card is important don’t always trust the updates Microsoft supplies you with, Go directly to the card manufacture site.
Also, if you’re running add-ons this could hinder the cards ability to function correctly. I would disable all addons, scan your system for trackers, etc. Worse case you may need a new card. I found that just upping the ram from 8GB to 32GM worked wonders.
Select your dedicated graphics card via ingame settings& in the graphic settings on your pc for wow. It’s selected as integrated by default.
my m2 max has it too. it just means your graphics card is branded “low power”. must be a green marketing thing. 
your computer is using it fine.
