Hello, this is a follow up on the now closed US post about both classic and retail wow freezing for a good few seconds at random while streaming on discord (basic stream).
The settings suggested by this post did not work for me:
Discord streaming freezes WoW
However, fiddling with the Max Foreground FPS Toggle in the in-game Graphics settings did. My max FPS is 240 so I lowered it to 120 and it stopped freezing. After restarting the game it started freezing again so I changed it to 119. I think it works with any FPS as long as you change the value while streaming.
Alternatively, switching to windowed mode also helped.
