Vehicle is stuck in the ground! HELP! in ARMA 3 - ADDONS - CONFIGS & SCRIPTING Posted April 11, 2016 Okay, I got the car driving. However, I made it happen by commenting out the line in the config which is simulation = "carx";... So now I will not have physx if what I read was correct. I'm guessing that commenting out that line turns off all of the Physx settings.
