Shadows screen flicker

Is anyone else gameplay flickering when turning the shadows up from low? and is there anyway of fixing this?
I noticed it happens a lot in Revendreth.
Also running a GTX 1660ti

try Vertical Sync set to disabled and the Graphics Card set not on Auto Detect? it may fix the flickering of the unoptimized settings that the game engine uses

I chose my graphics card and it seemed to have fixed it. Thanks!
