Hey Guys and Girls,I've just recieved X-Plane 10 and was wondering how I turn the AI off. I would rather use that extra processing power to up my scenery and make the world more appealing than having 4(Seeing as i'm using 4 cores) AI planes fly around.(Sorry if it has been answered, i've tried looking around, but to no luck so far.)Cheers,Matt

In sim top menu->Aircraft->Aircraft and Situations->Number of aircraft. Change it to 1 (yours)

Thanks Goran for the quick reply Matt

...having 4 (Seeing as i'm using 4 cores) AI planes fly around.

I think Austin's description of how the AI works was confusing. While the AI aircraft will use all available cores (one per AI if you have them), you don't need to dedicate one core per AI. In my case, I have a 6-core CPU but 15 AI planes enabled with no significant loss of performance.
