Motion Driver for GP-Bikes bike racing sim
A beta version is available
for the bike racing sim
GP-Bikes (beta14). The download is on the
Introduction page - use V3.420 for
GP-Bikes Beta14. Earlier versions of the motion software do
not support GP-Bikes beta14.
This version of the motion driver
still uses the GP-Bikes memory-mapped file GPBProxyObject for its
telemetry data. This is enabled using GP-Bikes Proxy plugin
provided in the GP-Bikes installation.
To activate the plugin the "proxy.dlo" file in the "gpbikes\plugins"
folder of the GP-Bikes installation folder should be copied to the
GP-Bikes main installation folder.
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 GPBikes motion driver for obvious reasons.
The default .bff config files in
the GPBikes motion driver zip file contain cue settings better
suited to the faster dynamics of the racing bike 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 so much (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.
Also to better simulate bike lean
the roll cue is mainly set to follow bike bank angle rather than
sustained lateral acceleration. Again you may wish to experiment
Remember you can use the Drive
and Hold hot-keys or hot-buttons which are defined in your .bff cue
The refresh rate of the motion
driver output can be increased up to the data refresh rate of the
GPBikes telemetry data output using .bff configuration file
Use with Fullscreen Mode:
If you are using GPBikes in full
screen mode then you will need to start the motion driver before you
start the sim, and then use the motion software hot keys/buttons to
switch the motion software between Drive and Hold when it is in the
If the motion software is started
first it will indicate that GPBikes has not been found and allow the
user to instruct it to wait. Once GPBikes has been started in full
screen mode, the motion software will automatically proceed in the
background and will become active once a bike is on the track. Then
use the hold/drive hot keys/buttons to switch the motion software
Hot keys or buttons can be set
manually in the .bff configutation file.
If you find any bugs or strange
behaviours in the beta version then please let me know.
