Hello,I got the problem that all AI-Traffic which is related to Missions (F-16 Missions, Patrouille Suisse Missions) is slightly stuttering constantly (like 0,5-1m forward an backward 4 times per second)Any suggestions to fix that?(Googling for stuttering ai traffic didn't bring meaningful results ;-) )MY SYSTEM:-----------------My system runs fine (30-35fps) limited by extenal FPS-Limiter.fsx.cfg is optimized by webtool: http://www.venetubo.com/fsx.htmland BufferPools are offSystem:phenom 2 x4 955 @ 3,7 @ 50°C4gb ramgforce 280gtx530w psu

If you have a high FPS and are flying next to AI you will see what you describe. Force your FPS to 20, take a test flight and see if that fixes it. From what I have read what you see can happen if your FPS is over 30. How bad it gets is probably different from system to system.

Try loading FSX without the FPS Limiter, and set FPS to 30 inside FSX...

OK..thanks for your replies....I will try that...although I suspect that performance will be bad when limitting to 20fps or using FSX-internal limitting

I said 30 FPS, not 20...
