RFactor has a detailed interface during offline race sessions or online games, allowing players to control the mechanical setup of their cars, chat to other players and enter the racing arena in their vehicle. The isiMotor2 engine was also used in many other simulation games, and in rFpro. The isiMotor2 on which the game is based is a direct successor to the engine used in previous titles developed by ISI, most notably F1 Challenge '99–'02, released through EA Sports.

RFactor was developed by Image Space Incorporated (ISI), which has been developing simulators since the early 1990s for both commercial and military purposes.

Released in November 2005, rFactor did not have much competition in this market, but it featured many technical advances in tire modeling, complex aerodynamics and a 15 degrees of freedom physics engine. rFactor aimed to be the most accurate race simulator of its time. On the physic side, the Gentlemen Racers team has made a big work on integrating features such are ultra flex chassis, tires with CPM2 technology, accurate aerodynamics, advanced FFB and suspension geometry.RFactor is a computer racing simulator designed with the ability to run any type of four-wheeled vehicle from street cars to open wheel cars of any era. A big work was made to reproduce most of the real cars paint shemes, coming from real championships from Europe and North America. All the cars are build with a lot of details and quality, with powerfull DX11 shaders and fully integrated technologies such as rain drops reproduction, les flare headlights, animation of drivers and wipers, and much more.
