Vibrating AI traffic, has anyone ever seen this besides me?

[idahosurge]

My new system is less than two months old and this is the first time that I have seen this, it does this with both the default FSX AI and MyTrafficX AI.

It is only when the AI is in the air, while on the ground the AI does not do it, even when they are moving along a taxi path.

The best way that I can think of to describe it is for you to put your hand in front of your face and move it left to right to left to right and keep doing it, do this at a moderate pace, this is what the AI planes look like if I am flying beside them. They vibrate forwards, backwards, forward, etc. all the while continually moving forward on their flight plan. They do not vibrate left or right, only front to back and they follow the flight plan in a straight line.

I tried to take a screen shot, but the vibration is slow enough that it does not show up in a screen shot.

Does anyone have any ideas on how to get this to stop, I really would rather not go through the whole uninstall/reinstall routine. I have had FSX on two other PC's and have never had this happen before. I just noticed this last week on this PC and I can not say for sure if it just started or if it has been like this since I installed FSX on this PC in September.

My system is a R3E, 980X @ 4.41GHz, ram 6GB 6-7-6-18 @ 1600MHz, GTX 480, I have this set up per NickN's Win7/FSX guide, the drives are defragged and everything. This is the only issue, no stutters or anything, just this vibrating AI. I doubt that it matters, but my FPS is over 30 anywhere I go and it spikes into the 100's, plus like I said, no stutters, the sim is smooth as silk, except for this AI problem. Even when I am flying next to the AI and it is vibrating, the ground, sky, water, everything else is rock solid, no blurries or anything.

Thanks for any help or ideas!

Try locking your frame rate at 29FPS in the FSX display settings. I'm not sure if it applies to AI traffic, although I'm almost certain that it does... FSX is probably redrawing your screen faster than it can compute the position of the AI traffic. This is the case in multiplayer, which projects multiplayer aircraft as AI aircraft.

This is why we must lock our frames below 30fps for a successful formation flight in FSX.

Hope it helps. I personally never fly the game in single player.

Lock your fps at 30, that should fix it. When you have it at a high fps you are going to get the shimmy effect, especially when using FSrecorder.

Chris, I guess we posted at the same minute.

Thanks Gents, that was it!
