Hi! So whenever I move my camera the screen becomes blurry. Almost pixelated. Is there a quick fix for it ? Thanks 
You may want to go into settings (cog wheel)and turn on smooth shading.
If you have post process on then the screen noise occurs as you move the view and the image is being reprocessed in realtime. This even happens within the most powerful realtime PC apps such as octane & is just something you have to put up with. Try turning off post process and there will be no noise.
