=================================================================  
(1) Q. What changes are made to CART Precision Racing when I
install the patch?

A. When you install the patch, you can expect the following
changes to CART Precision Racing: Improved graphics performance
in both software and hardware rendering, controls in the game to
set brightness for tracks and objects, a null-zone control that
helps you tune your controller's sensitivity, improved default
garage setups, improvements in the artificial intelligence
(computer-controlled cars), additional documentation in the
online Help file, FAQ, and readme files, and bug fixes.

=================================================================
(2) Q. How can I make the game run faster?

A. While you are driving, press LEFT BRACKET ([) to reduce the
size of the simulation window and improve frame rate. Press RIGHT
BRACKET (]) to increase the size of the simulation window.

You can also set the default size of the simulation window using
the Window Size slider control in the Graphic Options
dialog box (Graphics command on the Options menu).To reduce the
size of the simulation window and improve frame rate, drag
the Window Size slider control to the left.

Reducing the clipping pane, which affects how far ahead you
can see in your forward field of view, can also make the game
run faster. While you are driving, press CTRL+H to reduce the
distance you can see in front of you. (To increase the distance,
press CTRL+F.)

You can also set the default clipping pane using the Clipping
Pane slider control in the Graphic Options dialog box (Graphics
command on the Options menu). To reduce the clipping pane, drag
the Clipping Pane slider control to the left.

Other suggestions to make the game run faster: Experiment with
turning Graphics options (Graphics command on the Options menu)
on and off to find the right combination of graphics and speed.
For example, set Image Quality to Good, turn off the Textured
Sky, Draw Hills, and Track-Side Objects options. You can also
try setting Tire Effects to Tracks Only or None to speed up
the game.

Reducing the number of computer opponents you're racing against
may also make the game run faster. To reduce the number of
computer opponents, click Realism on the Options menu, and then
drag the Maximum Field Size (Single Player) to the left to 
specify the number of opponents, and then click OK.


================================================================
(2) Q. How do I hook up my steering wheel and pedals to work
correctly with CART Precision Racing? 

A. For complete instructions on how to install specific types of
race car controllers for use with CART Precision Racing, see the
"Configuring Your Race Car Controller" section of Gameplay Help
(Help menu in CART Precision Racing), or the "Controller
Configuration Notes and Troubleshooting" section of readme.txt
(included in the folder where you installed CART Precision
Racing). These sections include topics on installing the
following types of controllers: ThrustMaster NASCAR (R) Pro
Racing Wheel (outside U.S., ThrustMaster Formula One Racing
Wheel), ThrustMaster Formula T1 and T2, ThrustMaster Grand
Prix 1, and CH Products Pro.


=================================================================
(3) Q. When switching views while driving, what's the fastest way
to switch back to cockpit view for my car?

A. Press HOME to return to cockpit view from any game view.
(You can change views while driving by pressing V; you can
also jump into your opponents' cockpits while they're driving
by pressing K.)


=================================================================
(4) Q. The game looks kind of dark on my machine. Is there
anything I can do to fix this?

A. Some computer monitors and some video adapters have a dark
gamma setup, which can be contribute to a dark appearance.
Check the brightness and contrast controls on your monitor. If
you have a 3DFX control panel, you should be able to adjust the
gamma there.

Also, when you set Image Quality to Best (Slower), you can use
the Object Brightness slider control (Graphics command on the
Options menu) to make adjustments.

Finally, setting Image Quality to Good (Graphics command on
the Options menu) can also change some of the lighting effects,
which may make things brighter.


=================================================================
(5) Q. I'm running CART Precision Racing using Hardware
Acceleration, and I'm not getting the results I expected. Is
there anything I can do?

A. First, confirm that you have Direct3D (Most Hardware) selected
in the Renderer list box (Graphics command on the Options menu).
Second, when you start a race, press F4 to switch to full-screen
mode (no menu bar visible across the top of the screen). This is
crucial, since Hardware Acceleration only works in full-screen
mode.


================================================================
(6) Q. How can I reduce the "popping" effect of buildings and
trackside objects in my forward field of view while I'm driving?

A. While you are driving, press CTRL+F to increase the distance
you can see in front of you. This reduces the "popping" effect,
where billboards, flag stands, and other scenery objects in your
forward field of view appear to suddenly "pop" into view. If the
game runs too slowly as you increase the distance, reduce the
distance by pressing CTRL+H. You can also set the default forward
field of view by adjusting the Clipping Pane slider control in
the Graphic Options dialog box (Graphics command on the Options
menu).


=================================================================
(7) Q. Why do I hear a "banging" noise when I set the boost
pressure past 5?

A. The noise you are hearing is the pop-off valve that controls
maximum boost pressure of the turbo charger. In the real world,
CART teams are limited to 40 inches of boost pressure. To
regulate the pressure, a pop-off valve, or waste gate, is fitted
on the turbo (it's the round thing you see sticking up on the
cowling behind the driver's head.) When the boost pressure exceeds
40 inches in the turbo charger, the waste gate opens up and
releases the excess pressure, producing the "banging" noise. You
don't want this to happen in real life because the pressure drops
well below 40, which causes a temporary but substantial loss in
horsepower.

You can see this happening in the game by setting up your Pi
dashboard to display boost pressure (Pi Display Setup command
on the Options menu). Once you've done this, play with the boost
knob and notice how the pressure changes. When its at 5, the
pressure is 40; when you move it to 6, the pressure drops
drastically because the waste gate is constantly opening. 


=================================================================
(8) Q. What's that noise I hear when I'm driving in the pit lane?

A. The noise you hear when you're driving in the pit lane is the
sound of your car's rev-limiter kicking into to control your
speed through the pits. The rev-limiter is a device used on all
CART cars to limit the RPMs and the cars' speed to a certain
preset value specified by CART officials. The rev-limiter in
CART Precision Racing prevents drivers from exceeding the 60 MPH 
speed limit while driving through the pit area.


=================================================================
(9) Q. Why does the game sometimes appear to pause briefly while
I'm driving?

A. If you have other programs running in the background while you
are playing CART Precision Racing, you may experience brief
pauses while you're playing. Hard disk activity, incoming email,
and other background activities can cause the pauses. It is
highly recommended that you exit all other programs before
starting CART Precision Racing.

If you are using a digital controller and you are experiencing
brief pauses while you are playing the game, making a change to
your game controller configuration may also resolve the problem.
Follow these steps: Click Start, point to Settings, click Control
Panel, and then double-click Game Controllers. Click Advanced,
and then click the Poll With Interrupts Enabled check box.
Click OK.

Important note: Turning on Poll With Interrupts Enabled may
improve or worsen your joystick control. In general, turning
on this option is recommended only for digital controllers,
not analog controllers.


=================================================================
(10) Q. Can I change the paint job on the cars featured in the
game?

A. A car painting utility kit that allows you to create your own
custom car textures for all cars featured in CART Precision
Racing is available for download from the World Wide Web.
To download this paint kit, connect to the Apex Web site,
located at the URL listed below, and go to the Downloads page
(no direct URL):

=================================================================
(11) Q. Is there anything I can do to make my joystick (or
steering wheel) feel a little less twitchy?

A. Yes. Adjusting the Null Zone setting for your joystick or
steering wheel may help make your driving experience a little
less twitchy. To increase the Null Zone setting and reduce the
twitchiness, click Controls on the Options menu, confirm that
the controller you want to adjust is selected under Primary
Driving Control, and then click Customize Controller. Drag the
Null Zone slider control to the right to increase the Null Zone
setting. You may have to experiment to find the perfect setting
for your driving style.


=================================================================
(12) Q. Can I adjust the amount of force I can feel with my force
feedback controller?

A. Yes. By adjusting the Crash Force and Center Spring settings,
you can tweak the feel and response of your force feedback
controller. To adjust the settings, click Controls on the Options
menu, and then click Customize Controller. Confirm that the Use
Force Feedback check box is selected, and then drag the Crash
Force and Center Spring slider controls to adjust the amount of
force you can feel with your force feedback controller. You may
have to experiment to find the perfect settings for your force
feedback style.  

=================================================================
(13) Q. Is the way the car handles on sand and grass different
when you're driving at the Professional skill level?

A. Yes. When you're driving at the Professional skill level, you
can expect a challenging and slippery ride when you go off on
grass or gravel. In interviews, real-world CART drivers often
compare driving on sand and grass to "being on ice," and that
sensation is included in the game for those who are skilled
enough to drive at the Professional Skill level. If you can't
handle the challenge, you may want to consider driving under
the Rookie or Intermediate skill levels. 


=================================================================
(14) Q. How can I change the name of one of the CART drivers in
the game?

A. You can change the names of the drivers featured in CART
Precision Racing by following these steps: Open extras.ini (file
located in the system folder where you installed CART Precision
Racing). Search for the name you want to change, delete it, and
then type in the new name you want to use. Save and close the
file. You may have to restart Windows in order for the change to
take effect.


================================================================
(15) Q. How can I adjust the volume of the music in the game?

A. Use the Windows 95 Volume Control to set your audio level, 
and keep in mind that you can insert and play music from any
audio CD while you are playing CART Precision Racing (works best
if you chose the Complete option when you installed the game;
otherwise, you may have to swap CDs in the drive.)


===============================================================
(16) Q. How can I adjust the angle of the rear view mirrors?

A. You can adjust the angle of the rear view mirrors on the 
Miscellaneous tab in the Garage. Use the Test Drive button
to head out onto the track to check your adjustments


===============================================================
(17) Q. How can I display frame rate?

A. Type FRAME while you are driving. The frame rate calculation
appears in the lower right corner of the screen. To turn it off,
type FRAME again.


==============================================================
(18) Q. Can I view Instant Replay files in full-screen mode?
 
A. Yes. Click the Zoom button on the Instant Replay screen to
play Instant Replay files in full-screen mode. Press ESC when
you're finished.


==============================================================
(19) Q. When I'm driving at the Rookie or Intermediate skill
level, are my computer opponents driving slowly?

A. In Rookie and Intermediate modes, some of your computer
opponents may drive slowly--they are designed to help beginners
get comfortable behind the wheel and enjoy the game. When you're
ready for fast opponents, try racing at the Professional
skill level (Driving Aids command on the Options menu).


==============================================================
(20) Q. Is there any way to change the behavior of computer
opponents more precisely than switching skill levels?

A. Yes, you can change the skill of your computer opponents
more precisely than the Rookie, Intermediate, and Professional
skill levels included in the game. Here's how: Open cart.ini
(located in the system folder where you installed CART
Precision Racing). Find the "skilltrack" entries, which
include each track name followed by 6 numbers. Find the
track that you want to edit and adjust the numbers, which are
organized according to the following format:
- <rookie_min, rookie_max, intermediate_min, intermediate_max,
professional_min, professional_max>.
The numbers are % (999=100%), and the "min" number is the
setting for the slowest computer opponent car on the track,
and the "max" number is the fastest computer opponent car.

 
==============================================================
(21) Q. How does increasing or decreasing the steering ratio
setting affect handling on tight corners, like Laguna Seca's
Corkscrew?

A. The steering ratio setting, on the Suspension (Axle) tab in
the Garage, affects how much steering angle you get for a given
amount of input from your joystick or wheel. On ovals, a low
ratio is typically used, since the turns are all fast and large
radius. On road/street circuits, more steering ratio is used so
that high steering angles are available for super-tight hairpins.
With too high a steering ratio, you can get some undesirable
results. For example, you may find the car twitchy at speed
because small inputs from your wheel/joystick result in larger
steering angles. 
 
Driving with too high a steering ratio setting can also mean
you'll have trouble cornering. If, in the course of driving
Laguna Seca, you are using full steering lock anywhere other
than in 1st or 2nd gear turns, you are probably generating
overly high slip angles on the front wheels. You can tell if the
"tire squeal" noise is excessive and the car doesn't turn
in well. Many drivers assume this is terminal understeer; what
they don't realize is that it isn't a setup problem, it's a
driver problem. If you practice turning in earlier, WITH LESS
WHEEL, you'll find the tires stick better and the car turns in
dramatically better. Also, since you're not scrubbing off speed,
you'll cut your lap times as well. More steering ratio makes this
harder to do. If you're having trouble getting the car to turn
in, and you find your wheel/joystick cranked over full lock on
most turns, try REDUCING the steering ratio setting. Once you get
the hang of driving with smaller slip angles, increase it so you
have it available for slow turns.
 
Remember, too, that once the wheels are cranked to full lock
(at low speed), almost no acceleration is available to you. Why?
Because in 1st or 2nd gear, any touch of the throttle will
transfer virtually all the weight off the front wheels and the
car will understeer badly. Wait until the wheel is almost
straight before getting on the gas.
 
A helpful tool included in CART Precision Racing is Pi Analysis.
Use the graph of steering angle to help refine your steering
technique. If you see large steering angles on large radius
turns, you're probably cranking on the wheel excessively and
getting a lot of push as a result.
 
If you find yourself going through a hairpin in 1st or 2nd gear
and you still can't get around the turn, before you crank up the
steering angle, use Pi Analysis to check your speed through the
turn. Because you have limited sensations of speed in the game,
you can be going a lot faster than you think when you give the
car full steering lock. If you hear tire squeal at very slow
turns, you are probably trying to turn faster than the adhesion
of the front tires will allow. Try braking longer or starting
earlier to kill more speed before turning in.
 
There are tracks where you need a lot of steering angle just
to get around (Vancouver is an excellent example). You'll want
a steering ratio of 11 for Vancouver to get your around the two
really tight 1st gear turns, but then you have to be extra
careful to avoid overdriving the car on the faster turns.
