Distant scenery objects not blending with scenery

Hey all,

Hope everyone is well

My sim seams to have developed this strange problem that I'm sure many of you must have come across in the past. As you can see in the following picture the buildings in the background are not blending in with the background/ground. It doesn't look like they are floating it just looks like a blending issue.

Is anyone able to shed some light on the matter? I have just managed to get the Sim running nice and smooth now I notice this. I'm at my wits end as I just want to settle down and fly instead of having to play around with settings ETC

I have Fiber Frame Time Fraction = 0.01 in my .CFG could this be related??

This particular picture was taken in ORBX Germany region but have noticed the same thing in NIR also - latest library installed.

I have since been told FTX Vectors could be causing this though I'm sure I disabled it in the scenery editor tool

Please help me finally relax and fly

thanks for your time everyone
