Informed by Nicoooo! in the Discord Server that Asobo has confirmed the “Render Scaling” in SU6 is broken.  Night Lightings will disappear when the scale is set below 100 and lights will float when the scale is greater than 100.  The error will be resolved in the coming hotfix.

Since I mostly fly in day time, I’ll keep the scale at 90 and change it to 100 when necessary.  Thanks Nicoooo!
