Hi PixShake -

I am not getting the same results that you are showing in your pictures above. Can you look at a few of the following settings and make sure that they are set as listed: Your Engine Scalability Settings should be set to EPIC, your Material Quality Level should be set to High, and the Preview Rendering Level should be set at
Shader Model 5. Also are you experiencing this issue in all of your projects?

Thank You and Let me know -
