The sophistication and intricacy of these simulators continued to grow, and in 2008 the "Digital Combat Simulator (DCS)" released "," the first of a series of simulations that featured a complete and detailed cockpit with all the relevant switches accurately modelled and functional, and mapped over 500 key-commands. DCS also supported a variety of input devices aside from the traditional joystick, throttle, and pedals, featuring built-in support for TrackIR and Virtual Reality with 6 degrees of freedom which, in conjunction with the interactive 3D-cockpit, created a very realistic experience.
