SCAWEN:
After thze recent updates, the physics-engine became that demanding, that whe had to completely cut it back to 3 basic values: acceleration rate, decceleration rate, turning rate.
To keep the community happy anyway, we added nitrous oxide injections to all cars, increased spoiler sizes and added a "base volume" option to the sound settings.
