The game will immediately exit (crash) if you launch it while SteamVR is running and Desktop Game Theatre is enabled. Please close SteamVR or disable Desktop Game Theatre before launching the game.
The force feedback of a steering wheel may stop working when you enter the VR mode. It appears that the problem occurs only for Thrustmaster racing wheels. Logitech racing wheels do not seem to be affected by the VR mode. We are still investigating the problem.
Webinar: The new vehicle physics engine by Raving Bots
A short webinar in which the author of the new vehicle physics engine used in eXpanSIM explains how it works and compares his original solution with other existing approaches:

Patch update #13: Truck interiors
What's new
Added a new interior model to the fire truck
Added a new interior model to the diesel semi-trucks

Updated vehicle previews
Known issues
The game will immediately exit (crash) if you launch it while SteamVR is running. Please close SteamVR before you start the game. SteamVR will be automatically launched later when you choose the VR mode from the in-game menu. The problem is caused by "Use Desktop Game Theatre while SteamVR is active" that is enabled by default.

Patch update #12: Vintage cars
What's new
Added a classic German car inspired by Mercedes-Benz W123
Added a classic American car inspired by Packard Predictor
Added an atomic era classic car inspired by Pontiac Star Chief
Physics
Improved continuous track suspension in tracked vehicles
Adjusted the torque curves of tank engines
Fixed the collision shapes of tank hulls
Increased physics precision on the Testing Ground map (tesselated large triangles)
Enabled the enhanced determinism of the physics simulation
Visuals
Adjusted the sizes of track plates in tanks
Improved the observer's camera view
Polished details on the Tank Biathlon map
Fixed gauge pointers in vehicle interiors
Audio
Enabled the audio volume controls in the settings panel (it was added earlier, but it was visible only in the debug build, so it was overlooked)
Other
Updated the project to Unity 2019.3
