Texture Problems

Hi there.Today I performed my Virgin Atlantic 19 from EGLL to KSFO after I reinstalled my FS and all the Addons and encountered a strange texture problem at San Francisco. All the textures seemed to remain blurred, even the ones right underneath the plane. Even as I descended to 4000 feet and below everything looked very ugly und blurry.I've heard that you somehow can influnece the blur radius...may this has something to do with it?My Specs:Intel 2.664 Gigs of RamAsus GeForce 260 (overclocked version)Vista 32 BitAddonsFS Global 2008Mega Airport HeathrowTampa KSFOMega Scenery San FranciscoActive Sky 6.5Radar Contact 4.3PMDG 747FS2CrewAESDsiplay Setup:I think except of the AA (which is actually turned of, because I use the "nhancer"-tool) all the switches are at the full right position.Resolution 1920*1200 :)Regardshirn
