ĭue to the complexity and demands of mimicking real-life driving, racing sims require faster computers to run effectively, as well as a steering wheel and pedals for the throttle and brakes for the immersion. FiA, the governing body for many auto racing events including Formula One, use various sim racing platforms such as Gran Turismo, Assetto Corsa Competizione and iRacing to host sanctioned racing events. It is this level of difficulty that distinguishes sim racing from arcade racing-style driving games where real-world variables are taken out of the equation and the principal objective is to create a sense of speed as opposed to a sense of realism. To be competitive in sim racing, a driver must understand all aspects of car handling that make real-world racing so difficult, such as threshold braking, how to maintain control of a car as the tires lose traction, and how properly to enter and exit a turn without sacrificing speed. Simulated racing or racing simulation, commonly known as simply sim racing, are the collective terms for racing game software that attempts to accurately simulate auto racing, complete with real-world variables such as fuel usage, damage, tire wear and grip, and suspension settings. Jann Mardenborough, a sim racer became a professional Nissan racing driver by playing Gran Turismo. For professional simulators, see Driving simulator.
