Specific blurry problemo

I know, not another blurries post. I have looked good and hard but mine is specific to what I believe to be the LOD radius. However I have edited mine to 6.5 which should give me a large radius around the aircraft than I am getting. If I am at 20,000 feet the radius of sharp textures is about 60 degrees below the horizon. Everything beyond is noticably blurry. This is everything visible in the FL300 and above. As you can see I have the proper equipment. These texture tiles never load beyond this radius so it is not a slow computer anyway. I noticed this after using Bojote's .cfg tweak which I am otherwise very happy with. Instead of reverting to my old one I would just like to find out which item was tweaked to cause this. I have done alot of reaserch and many .cfg tweaks, FFTF .5, texture max load 60, etc. But I think this is a different issue than the graphics card being able to keep up. It looks like a deliberat blurry radius that never loads even while stationary in slew.Thanks for any advise
