I make a scene in 2.81.16
Eevee Render
I have some emission neon light and some reflection in the ground but the scene have so many unwanted flickering light as you can see in the video !
Iβd try increasing the render sample count to 64+ at least. + The render settings for SSR doesnβt seem to make much sense to me. Iβd reset them and even try increasing the SSR thickness over the default.
