improving the fly-by camera?

Hey guys, I was pretty much fed up with fsx default cameras so I deleted all of them from the cameras.cfg and left cockpit view and the fly-by view. I use ezdok to manage other views. Thing is, about the fly-by cam is that things always seem blurry in the background.. I recalled reading somewhere that fsx engine blurs textures when a huge zoom factor is used, so I toned down fly-by 'InitialZoom' to 0.7 and it's helping, but very slightly.. I'm just thinking what other parameters should come into play when tweaking this camera? Maybe someone already has a nice config I could use? Thanks!
