15. 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:

Installation of the motion driver is mainly the same as the other versions - see section 2.

Operation:

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 with this.

Remember you can use the Drive and Hold hot-keys or hot-buttons which are defined in your .bff cue configuration file.

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 parameter MD_Delay.

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 background.

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 mode.

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.
