I am running quite a powerful computer, yet I have a scenery problem, I have ORBX scenery and Pilots mesh along with some UK2000 Airports. On a flight in my PMDG 777-300 from Glasgow to Gatwick my scenery is great, after 10 mins or so scenery goes blurred finally goes to a mushy green texture with a definite line across scenery and no scenery. Has anyone got any ideas what may be causing this

Thanks in Advance
Alan
