I was looking for the setting that determines the level of details over distance. This seems to do it. I set it at 200 to see if it helped and it did. This appears the be the hardest impact on performance but I did not notice any difference in performance

My guess is that setting terrain LOD to 200 just uses more VRam and possibly Ram, as long as you don’t hit the limits on those it doesn’t seen to affect the fps too much.
But I am running at a limited 30 fps on my system so I have a bit of GPU headroom left for better visuals anyway.
That depends on where you’re flying.I do not notice an impact either when flying smaller planes in less demanding areas.I noticed stuttering on 200 lets say I fly the 747 or a320 into LAX or JFK.It can have a huge performance impact depending on your specs,where you fly what you fly.
Agreed, when flying airliners, this setting to 200 does seem to do much of an improvement. Still having issues w/ specific cities looking quite awful.
I notice that flying in Glacier National Park, the distant mountains were not blurred. that is what I was trying to avoid. I did not really see any difference around Southern Ca. I am running at 30FPS now but have it set at 60. I might try 30 and see what happens but I am not getting tearing or jumpy effects on a turn with the scenery. I was running 4K but switched to 3K, did not really see any difference but FPS went higher and the scenery is smoothness is better. I set the display at 60hz refresh from the default of 24 on the GTX 1080. Over all the sim seems to run very quiet so that makes me a happy camper.
