Lagging like crazy with DX12.Why?

So i got a good PC setup. But when i run DX12, the game lags like crazy and i cant do anything.

If i got down to DX11 Legacy , then everything works fine.

my setup:
ryzen 9 5950x
Geforce 2080 TI Matrix
32GB ram

I can play all other games without problem in dx12, Conan exiles, BDO, COD the list keeps going.

Why dose DX12 not work correctly with wow?

There are known problems with the game after last patch - but that may not be what you got too.

Does the DX12 problem is in every zone/spot? Did you checked without any addons etc?

Without addons its still there.

Zone i dont know really, was in stormwind, could not do anything.

When the game is having this problem can you check Windows task manager - to see if something else is also very active? (some people got Windows wallpaper rotator to go crazy in the background)

Then if not get Latencymon, run it, run the game and when it starts having problems alt-tab to latencymon and check if it’s all red and if it is - does it point to Nvidia as the problem? (if you will have to remove Nvidia drivers with DDU, update board/audio drivers if present and install Nvidia drivers fresh).

Other problems could be weird “optimization” apps, SSD having problems (like if it’s getting close to full).
