Can someone explain to me Minimum and Maximum Cloud Draw Distance settings? I never know how these setting work (or what they do in the sim). Should the numbers be the same or different? Right now they are both at 90.

The cloud draw distance simply gives you the visible radius of rendered clouds around your airplane. If you set the minimum and maximum value identical, the draw distance will be stable at that value at all times. If you set different values, AS will use the smallest radius in situations where it makes sense to reduce the GPU load (for example, on the ground or right after passing the cloud layer), and use higher values if you climb higher above the clouds.
