I have an unusual problem which has stumped me for some time.For some reason I have to refresh my scenery as I fly along or it will not load! In other words I can find myself flying over blank scenery until I hit my refresh scenery key which causes the simulator to reload scenery. After I fly for a while I have to do it again! I have played with many settings in the FS9.cfg as well as display settings in the simulator, but nothing has worked.My CPU is 2.39 GHz; 2.0GB RAM; nVidia GT 220 GPU; Windows XP SP3. I have all my scenery on the operating system drive and the page file (3.072GB) is on another physical drive with its own partition.I would appreciate any help!Thanks!Airbus

One has to wonder what other applications and/or services are running in the background - all competing with FS2004 for CPU cycles.Have you checked into that? Such items as virus scans going on, indexing files, your e-mail client checking for new mesages and so on.Just a place to start looking.

Hi Opa:Thanks for your response! I already had disabled the indexing service and I am playing around with shutting down virus checking. I am using Microsoft Security Essentials and can easily shut it down. I have Alacrity PC some time ago so perhaps I need to go back to trying that again. Hopefully I can get this sorted out.Thanks!Airbus
