Hello, I tested Legacy Head Movement(from PCars2) and AMS2 default one in simple way by parking on the bank of daytona oval. The Legacy has a tendency to align with the horizon at low speeds, and the default setting is to show a movement that tries to show the vehicle's lean as much as possible. And the Legacy had an unnatural roll motion transition when exiting the bank and entering the flat area. Check out the differences to help you decide which one is better for you. Thanks! Pitch Up Legacy: head locked to horizon Legacy: side view AMS2 Default: AMS2 Default: side view Pitch down Legacy: Legacy: side view AMS2 Default: AMS2 Default: side view Roll Legacy: parking Legacy: moving AMS2 Default: parking AMS2 Default: moving
