But in my FS9 version, the Frames are down at 10-14 frames, at other airports i have 26 frames (locked at 26).The Frames are down with or without Ai-Traffic.
First, there's no way to even *start* diagnosing your issue, if you don't give us any clue about your hardware.
However, I find quite unlikely to have the scenery performing the *same* with AI or not, and with that low performances in FS9. I have better fps in FSX...
I can't say what fps you might expect, without knowing more about your system but, the simple fact you don't see any difference with traffic or not, lead to believe you have a serious configuration problem somewhere. You should see at *least* double fps with AI traffic off, if not more.
