New Collision Model
While nearly everyone tries to avoid them, collisions are a part of racing. With the November update, we have implemented some important physics updates that significantly change collisions in the game. These changes can be found across three different areas of the game:
1) We’ve improved energy dissipation between bodies, as well as the way tire friction is calculated during a collision. This is a global change, which results in “softer” collisions, where collisions absorb energy and the collision impulse happens over a longer period of time.
2) In multiplayer events, collisions are now resolved locally and blended when the game receives an update from other player(s) in the same multiplayer match. Effectively this means that multiplayer collisions now work like single-player collisions, even in high-latency scenarios.
3) A new Collision Assist setting scales the amount of body rotation a car can impart on another car in a crash. Players can choose to turn the Collision Assist on or off and players will have the option to create lobbies that use this assist (or ones that do not). This collision assist is meant to curb griefing; and a car hit by a car with this assist engaged will also receive the assist.
The sum of these changes means that contact and collisions feel much different in Forza 7 with this update. Car contact when side by side will result in fewer spins; tandem drifters will find that their cars will be more tolerant of tiny taps than before, and griefers dive-bombing into Turn 1 will have less of an effect on the rest of the field than before. In all, the new collision model is meant to bring car-to-car contact more in line with the real world, and also make the experience for players of all skill levels that much better.
