Motion Driver for Project CARS racing sim
A beta version is available
for the racing sim
Project CARS. The download is on the
Access to the racing sim telemetry
data is via the sim's shared memory area - there are no plugins
required. However the shared memory output of pCARS needs to be
enabled in the Options & Help area - under
Visuals-Hardware select the Use Shared Memory option.
IMPORTANT: this is BETA
software and may contain bugs - please use with care!
Installation of the motion driver
is mainly the same as the other versions - see
The software operation is mainly
as described in Section 3 Operation.
Some of the flight sim related
features such as heave movement recording due to turbulence etc are
not active in the pCARS motion driver for obvious reasons.
The default .bff config files in
the pCARS motion driver zip file contain cue settings better
suited to the faster dynamics of the racing car sim. You may wish to
experiment with them. Generally because the on-ground vehicle accelerations
are held for shorter durations before changing again rapidly there
is less need for washouts in the cue, so the sample configs don't
use acceleration washouts (other than where they are needed for basic cue
development - ie in the heave and yaw cues). The acceleration scaling to fit the cue limits may
also need to be adjusted to suit different vehicles.
NOTE: When pCARS leaves or
switches between a live driving session
the telemetry data can become erratic and it is best that the motion drive
is not left on Drive when this happens. By default therefore the
drive will switch to Hold at Start Pos mode whenever pCARS interface
returns to Race Central.
However it is
recommended that the user manually switches to Hold at Start Pos
whenever race mode is exited because the pCARS API telemetry data
does not detect all situations in which a live driving session ends.
Remember you can use the Drive
and Hold hot-keys or hot-buttons which are defined in your .bff cue
configuration file to do this.
The refresh rate of the motion
driver output can be increased up to the data refresh rate of the
pCARS telemetry data output using .bff configuration file
Use with Windowed Mode:
You will need to put pCARS into
windowed mode in order to first run the motion software and make all
your cue settings and adjustments.
To do this go the Options &
Help area and under Visuals-Performance select the
Windowed option. You should also set the Resolution small enough
to be able to see both pCARS and the 6DOF motion software at the
Use with Fullscreen Mode:
There doesn't seem to be a way at
the moment of switching pCARS in and out of Windowed mode on the
fly. So if you wish to use pCARS in fullscreen mode then the motion
software needs to be started before pCARS is started.
So Start the motion software
first, then once pCARS starts the motion software will complete its
startup routine in the background. When you are ready for motion use
either your assigned hot keys or joystick hot buttons to switch the
motion software in /out of Drive mode.
The Drive and Hold hotbuttons or keys
can be set manually in your .bff configuration file.
If you find any bugs or strange
behaviours in the beta version then please let me know.
