         Frames Per Second adjuster for Grand Prix/World Circuit
         =======================================================

This is a little program which can alter the Frames Per Second option stored
in the F1PREFS.DAT file; it can go outside the normal range, so that those
of us with fast Pentiums can select 50 FPS and so on. It does NOT touch your
GP.EXE file, or any file other than the preferences file.

When used with no arguments, it will attempt to open "f1prefs.dat" in the
current directory and print the current value; the value is given as the
number of 300ths of a second between frames, ie. 10 would be 30 FPS. Anapproximate number of FPS is also given (the value will be slightly
inaccurate if the FPS setting is fractional).

One argument may be given, the name of a file to use instead of
"f1prefs.dat". To set the FPS, use the "-period" option, eg.
	gpfps -period 10
	gpfps -fps 33

Note that the FPS option rounds the period up, so if you ask for 40 FPS,
you will get a period of 8 (37.5 FPS), not 7 (42.8 FPS). As I mentioned,
if you want to name a file other than "f1prefs.dat" you can, eg.
	gpfps exe-name\lfrs-cha.dat -fps 20

WARNING!!!
----------
Using a FPS setting which is too high can have a dramatic effect at the
start of a race. As soon as you move away, the car will slide left, and then
enter an unending spin. So, if you encounter this problem, reduce the frame
rate. Phoenix is a good track to try this at, as the occupancy is quite high
there. Just select "non-championship race" and go straight to the race. If
you get away okay, everything is fine, otherwise, increase the "-period"
value by 1 and try again.  As a rough guide, I can tell you that my Pentium 90 will only tolerate

period values down to 8 (that's 37.5 FPS) before it goes nuts.
Some tracks seem to not suffer this problem. Mexico City and Phoenix do;
Barcelona doesn't. I didn't try the others.

Furthermore, speeds above 50 FPS (period value of 6) appear to cause the
game to lockup at the manual protection screen. This is probably a
hard-wired game limitation.
