First thing you can try is delete the shader_cache folder
if that dont work try this
Verify Integrity of Game Files

and if you are using mods take them out and start a new save if that works then you know its a mod that create the problem.
A few things you can do to fix this main one is update or make sure your video card driver is newest driver as well as make sure all this is fully up to date
