I cannot seem to get rid of the choppy video problem. It happens when a plane gets close, 1000 yards or less. I have: turned the audio accelleration down, no preload anything, all the boxes are unchecked for water waves, detail and so on. I turned off all the background programs I could. Still happens. Have Latitude Laptop docked, 1.8 Ghz P-4, 1Gig memory, and a Radeon 256DDR PCI video card. Anything else I can try? I know of lesser systems and they don't run choppy. HELP!!!
