Hello, I have got a AMD 965 x4 BE, running in stock 3.4. Today I load FSX, on cold and dark, and meantime I had to check something on task manager, then noticed CPU start using 100 percent for like 10 seconds. Process was FSX. But in FSX, it was cold and dark, also no AI, no Airport vehicle, so almost no movement at all. Then I gave more test, different aircrafts, different airports, but it is exactly same, even timing same, every a minute, CPU goes to 100 percent for 10 seconds, and drops to idle. Just cant figure out, what make FSX use 100 percent CPU while nothing going on. I use decent graphic settings, and disabled preload, also AMD cool and quite is disabled, nothing important on background. Disconnected local network, but nevermind, Process is FSX, so something must be related to FSX. I use wideserver, so suspect if wideserver can cause this, as it will look for client. Have anyone got an idea ? Or is this something normal ? Thanks a lot.Salim

Unlesss you config FSX to pause when the FSX window loses focus, the FSX engine will continue loading scenery, moving the sun (or moon and stars), redrawing shadows, etc. as FSX-time goes by.Cheers,- jahman.

Thanks Jahman, so are you saying this is normal in FSX ? do you get same thing ? your cpu goes to, maybe not 100% but 50% when FSX time running and cpu trying to catch it ?
