I'm thinking of getting this game....

Actually, reducing the sensitivity settings slows the reaction response of the aircraft.

Last year Widar and myself conducted some experiments with the roll rate of the Spitfire IX in simulator mode with various control settings and found that at 100% the aircraft reacted noticeabily faster than when the settings were at 50%.

Reducing the setting of the controls has the same effect that a steering damper has on a motorcycle.... it slows up the reaction rate control it is attached so that a user with slower reaction abilities can cope.

I fly realistic and simulator with everything at 100% which allows me to make some snap turns and compensate for the twitchness of certain aircraft to positive advantage.

Quick and instinctive reactions soon become second nature with practice on real and sim modes.
