Changelog:

Simulation:

Physics

– Chain fence stiffness and damping have been reduced to prevent drivers riding up the walls and driving on the fence.

New Damage Model

– Some great advancements in our New Damage Model algorithms and processes have been made. These are system-wide changes that impact all vehicles that have the New Damage Model enabled. With our latest testing we are very happy with many of these results and are sending those updates your way. However, more work remains for some vehicles to be re-balanced with these changes. As such, we are only re-enabling the New Damage Model for the Street Stock car with this Patch 3. The remaining vehicles which will remain on Original Damage Model for the time being include:
– – ARCA Menards Chevrolet Impala
– – NASCAR Chevrolet Monte Carlo – 1987
– – NASCAR Ford Thunderbird – 1987
