               ****** MICROPROSE FORMULA ONE GRAND PRIX  ******

                    IBM PC TECHNICAL SUPPLEMENT ADDENDUM



1. Frame Rates And Processor Power / Speed.

Because  of the wide range of hardware available on the market today this 
simulation has several custom options to help you get the best 
performance from your equipment. 

Grand Prix / World Circuit will produce similar race times regardless of 
what type of processor you have, however more powerful machines will have 
the advantage of being able to use a higher "Frame Rate". 

This will make the simulation appear smoother and faster, if you wish the 
default settings may be changed as follows:

A) TEXTURED FILLS.

The keyboard letter "T" will toggle texturing on and off.  We 
recommend this function be turned off for 286 and slow speed 386 machines.


B) FRAME RATE.

Within the "Game options / Game" menu you can alter the frame rate of the 
simulation; provided your machine is powerful enough this will provide 
smoother 3D graphics.


C) PROCESSOR OCCUPANCY PERCENTAGE.

While the keyboard letter "O" is depressed during a race the screen will 
display the "Processor Occupancy percentage", this figure will fluctuate 
depending on how much work the processor is doing.

If the % remains well below 100 you may wish to increase the frame rate.

If the % rarely exceeds 100 you are getting maximum performance.

If the % is mostly over  100 you may wish to reduce the frame rate.


2. The Start-up Menu.

A new menu has been added at the very start of the game for those players
who want to get straight into the cockpit.

If you select 'Quick Race' at the prompt the program will start a quick race 
on a chosen circuit. The circuit and its details can be changed from within 
the GAME OPTIONS / QUICK RACE section as described on page four of the 
technical supplement.

You will race at Rookie level with all the help options switched on. This is 
a single race and you cannot race a season from the Quick Race option.
This option is the fastest way for a player to enjoy the action instantly.

If you select 'Main Menu' you will go into the main part of the game.


3. The File Selector.

When entering a filename you should be aware that the normal MS DOS / PC DOS 
restrictions apply;  

i.e. Names must not exceed 8 characters in length, punctuation characters are  
prohibited, only 1 dot is allowed, this separates the filename from the file
name extension.

4. In-game Sound Options.
If you press the + / - keys on the keyboard you can toggle the sound effects 
on and off. There are two levels of sound effects. If you press the minus key 
once the first level of sound effects are switced off. If you press it again
all sound effects are switched off.

Note: This option only works for Adlib, Roland and Soundblaster sound FX.


5. Car Set-ups.

A car set-up compromises the front and rear wing settings, brake balance,
race tyre choice and gear ratios. The mechanics of making changes in these 
areas are described in detail within the main manual.

Now, in addition to being able to save and load individual car set-ups (from 
the menu where you actually alter them), you can now create files (from the 
'Load/Save Game' menu accessible from the 'Main Menu') which hold your 
preferred car set-up for each of the sixteen circuits. As you hone each set-up
over time, you can add it to such a configuration file and so easily keep 
track of your most successful configurations.

There is another benefit to using this system. By default, any change that 
you make to your car set-up for a particular track affects the car's 
performance in all driving modes when on that track. However, the demands
on the car during free practise and qualifying (when the driver is 
experimenting with such things as the handling of the car and the choice of 
tyres) are very different to those on the day of the race itself.

More advanced drivers can tell the program to make this distinction by 
setting the 'Separate Race and Qualifying Car Set-ups' button in the 'Race 
Options' sub-menu (accessed through 'Game Options' in the 'Main Menu') to 
'Yes'.

From then on the program will determine whether any alteration made to
a car set-up is a 'qualifying' set-up (made during free practise or 
qualifying) or a 'race' set-up (made during pre-race practise; you cannot 
change the car set-up when actually racing), and will record it as such for
that track. When you do enter the cockpit the program chooses which set-up 
to use, based on which class of driving mode you have selected, and
configures the car accordingly.

You should note that with this feature enabled, the 'qualifying' set-up will
NOT be passed through to the 'race' set-up unless you manually transfer it
during pre-race practise.
