F1GP-Ed Documentation

This window contains settings which affect the wet weather:

Wet Race Probability
   Change the chance of a wet race (100% means all races will be wet).
 (default is 3%)

Wet at Phoenix
   Allows you to have a wet race in the USA (Phoenix).  Usually it is
impossible to do so.
 (default is off)

All Sessions Wet
   Makes wet practice and qualifying sessions possible.  The wet race
probability option affects these sessions too.
 (default is off)

Decide During Season
   This affects championship season games only.  Usually, F1GP calculates
which of the 16 races are to be wet before you begin your first race. This
information is stored in the save game file for later use.  This means that
altering the wet race probability during a season has no effect.  Enabling
this feature will change F1GP so that it ignores the previously calculated
wet race decisions, and instead the decision on a wet race is calculated on
the fly, just before you start each race.
