Why should I boost the frame rate?
Boosting the frame rate of the game makes a very noticeable difference when driving the car. Even an increase of 5-10 FPS can make a very visible difference when playing the game.
Another advantage of a high frame rate is that your lap times will be quicker, although I have no idea by how much. Below is an extract from the old F1GP FAQs:-
Using a frame rate of 25 fps means that you have 25 possibilities to perform an action (e.g. braking, accelerating) every second, whereas driving with 16 fps only allows you 16 "slots" per second.Assuming that a typical braking maneuver begins at 300 km/h (188 mph), this equals a speed of 83 m/s, so that at 25 fps you can take brake every 3.3 m as opposed to every 5.2 m when using 16 fps. During a normal lap including many braking maneuvers, this may affect the overall performance, not to mention techniques like pulsing the throttle.
How the frame rate is stored in F1GP
The frame rate is stored in the F1PREFS.DAT file as the value of the period (the number of 300ths of a second between frames). The following formulae are used to convert the two units:-
Frame Rate = 300 / Period
Period = 300 / Frame Rate
