what I tried before it got fixed:
The usual deleting cache, interface, wtf configs etc.
Downgraded GPU Driver
Forcing DX11, opengl or DX9
LAA (Large Address Aware)
Downgrading windows
FIXED! here's the list:
Re-installed windows,
Changed the directory of the game after new download&install
Download LAA (Large Address Aware)
Applied LAA on both wow.exe & Ascension.exe
Hope it stays fixed 😄
