Hello! I have been suffering the same pain. Suddently UE Editor was working horrible with a LOT of lag and was impossible to work with, just open a BP and move around the different codes and write new nodes and so, was totally maddening. Have been trying to update and also remove Geforce Experience but didnt helped so much.
But now I found what was causing terrible lag to UE Editor.
For some reason, the Anim Blueprint is lagging all the entire Editor so If I keep it open, it becomes hella laggy.
Why could that be happening?
Do I have something on my Anim BP to cause that?
Have anyone experienced the same as me?
Thank you.
