Since i have to have this value at around 40 to avoid the panning/loading stutter, can someone please tell me in a SIMPLE SHORT way what is this affecting ? I cant see visual difference only a difference in main thread behaviour. I was searching for it but all i found is that affecting airport traffic. It doesn't make sense because even being away from any airport its still causing main therd stutters.

It adds some details to objects. Indeed this does not have a lot of noticable visual effect. You can leave it at low settings.

No, those are affected by building and (probably) terrain LOD settings.

Objects are things like ground equipment and stuff...

You can check all sorts of setting and its effects here:

Thank you again ! so by that video it does only affecting airports stuff. 

I simply dont get this sim. Now with new patch my GPU is almost always 85% to 98% while my CPU is at around 17% to 25% and i still get main thread stutters here and there...
