Hallo there,Just out of curiosity - is it normal for the FS to engage the processor by 97-99%?I run it in windowed mode and just recently fired task manager to see what is going on out there.The memory usage seems pretty much normal (at 300-500MB), but the CPU shows to be constantly at 95-99%.Is this normal?My PC details:ASUS A7N8X deluxeAMD Athlon XP2700+ATI Radeon 98001GB 400Mhz 3200 memoryThanksDom

Hi Dom,Your CPU usage looks normal. MSFS will take all the power you can give it. Memory usage is dependent upon a number of variables (add-on airports, aircraft, weather, apps running w/the sim, etc.) but yours looks to be in the nominal range.Hope this helps,Greg

Thank you Greg,Your phenomenal help throughout this and other forums is invaluable.CheersDom
