If you go around saying you can't fly the game unless you have 70FPS then you are missleading people to think they can't play and that is an injustice.

Amen Animal!
I would say 40fps average would be enough for good solid game play. Then you can be pretty sure even in a high graphical deman area, your still going to be around the mid 20s.
But, You can still fly with lower frames. Remember AW and Big PAC. The harbor area around Hawaii was a killer. People would just avoid that area, you learned to compensate.
Below 25 smothness goes away quickly, at 15 things look pretty choppy. Yet I personaly can still fly at 15 (if thats as bad as it gets).
Let me list average frame rates like this, and this is strickly my opinion
15-25 poor barely flyable
25-35 OK might have some frame hits in bad situations
35-50 Good, should be smooth all the time.
50-75 Great looks fantastic all the time.
75-100 You now can claim your the most manly with a super box.
100+ The gods wish they were as cool as you
