Question: Why do you think that the AI was better before the 4.00 version?

Because back then AI was capable in turnfights and sometimes it was difficult to shoot him down. The difference of AI and player flight characteristics of the same aircraft was not so noticeable as it is now. In 4.08 I can easily outturn I-16 in a 109, before 4.00 it was not so possible. Current AI is good only at running, and player cannot outrun AI even in a faster plane.
Anyway, with previous AI offline was much more interesting.
