HI,When I am in the air in Spot Plane view, the plane undulates in an up & down wavelike motion. This is not a weather condition. I have updated the video card driver w/the ATI 4.12 driver & had not noticed this condition before. I also tried the 4.11 with the same results.Is it possible this driver update could cause this condition or what else could be the cause of it? The plane is steady when in Spot Plane view on the ground.Thanks,Bob AndersonWindows XP Pro w/SP2AMD Athlon XP2700A7N8X2 166 megahertz1024 MB DDRRadeon 97002 - 250GB WD 7200 RPM HD's

Hi. If I accelerate time in a flight I notice the plane moving up and down over a range of 100ft or so. This is on autopilot and I guess this is how it operates. I imagine that the wind has an effect as well, or maybe causes the reaction of the autopilot that I see and could this be the same thing you are seeing?

HI,Thanks for your reply.I have been running the Sim, at "normal" simulation rate & do not have any weather dialed in. I notice it whether the autopilot is on or off. I am really puzzled by it & don't seem to remember always having this conditionl

Hi there- this may seem a fairly? daft question but does the instrumentation show this movement? does the altimeter go up and down or anything else shimmy around? I'm just wondering if you could separate the thing out as to whether it was part of the game or part of your system that was causing the problem and then go from there.

Hello again,This condition is not noticed from the cockpit or VC view & not noticed in the instruments. The altimeter & the VSI is steady. It is only noticed in Spot Plane view. I have a feeling it is part of the system, not the game but am open to any suggestions.Thanks,Bob

Are you using Active Camera? There is an option that results in such behaviour. It

Hi Marcel,Yes I am using Active Camera & following your directions, I changed Spot turbulence rate from 0.25 (where it was set) to 0 & that solved my problem. I now get a steady level flight in Spot Plane view.I really appreciate your help as I had almost given up on this problem.Thanks again,Bob
