Due 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. While using a gamepad or even a mouse and keyboard, may suffice for most arcade-style driving games on home systems, it would not provide the same level of immersion and realism as using a racing wheel and pedals. In recent years, many sim racing experiences have been developed for consoles, such as the PlayStation and Xbox. While these games can be played with a controller, it is recommended that players invest in a racing wheel and pedals. With the development of online racing, the ability to drive against human opponents and computer AI offline is the closest many would come to driving cars on a real track. Even those who race in real-world competition use simulations for practice or for entertainment. With continued development of the physics engine software that forms the basis of these sims, as well as improved hardware (providing tactile feedback), the experience has become more realistic.
