The "Autogen draw distance" will probably mean little to the high and fast crowd, but you might be surprised with the effect at night.
At night this setting makes a huge difference, and probably will have little, if any, effect on your FPS.
Trust me. Move it off the Medium setting up to the Very High, or even the Extremely High setting.
This picture won't show what you get, not very well, but just try it.
You may find yourself flying more often at night.
BTW - HDR Brightness in on 1.12, Bloom on 1.00, Saturation on .80
