10. Motion Driver for Assetto Corsa racing sim

A beta version is available for the racing sim Assetto Corsa. The download is on the Introduction page.

Assetto Corsa is presently available as an early access version (v0.22.9 at the time of writing), so the motion driver software will probably be updated in time as the full release becomes available.

(Also now checked with V1.0.5b, NB toggle full screen mode now Alt+Enter for V1)

Access to the racing sim telemetry data is via the sim's shared memory areas - there are no plugins required.

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 section 2.


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 Assetto Corsa motion driver for obvious reasons.

The default .bff config files in the Assetto Corsa 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: The telemetry data shared memory areas don't become fully available until a Drive session is started from the Assetto Corsa Launcher. So it is best to start your Drive session first and then start the motion driver.

To switch Assetto Corsa in and out of Full Screen mode use the F11 button (now Alt+Enter in V1+).

The refresh rate of the motion driver output can be increased up to the data refresh rate of the Assetto Corsa telemetry data output using .bff configuration file parameter MD_Delay. 

If you find any bugs or strange behaviours in the beta version then please let me know.
