According to Sector3's Christopher Speed,
RaceRoom is created and maintained by 10-11 people. Since its release on February 12, 2013,
RaceRoom has been updated regularly with new features and content and has received significant improvements in all departments.
RaceRoom is built utilising
Image Space Incorporated's
isiMotor2 racing simulation game engine. Unlike prior SimBin & Sector3 Studio releases,
RaceRoom uses its own proprietary RendR graphics engine which is capable of different times of day, features commonly used post-processing effects and has native support for rain (rain is not featured in
Raceroom though).
RaceRoom also features a custom audio engine and is often cited as the benchmark sounding racing simulation on PC. In a March 2016 interview with
Inside Sim Racing, Sector 3's Jean-François Chardon stated that the original ISI code remaining in
RaceRoom is "less than 20 percent". The same month Christopher Speed posted a thread on the official Sector3 Studios forums titled 'In response to the so-called 'leak'... that a 'very small team investigating and evaluating newer technologies for the future'. Christopher Speed included an in-game screenshot of R3E running on Unreal Engine of a BMW Z4 GT3 at the
Circuit de Spa-Francorchamps. In a 2017 interview with racing simulation website Race Department, Christopher Speed revealed that
RaceRoom would replace the RendR graphics engine with
Unreal Engine 4 with
RaceRooms conversion to this engine aided by a partnership with SimBin Studios UK who were utilising this engine for the canceled
GTR 3 project.
Sector3 Studios works with real racecar drivers, using feedback from
Bruno Spengler,
Daniel Juncadella,
Kelvin van der Linde, and
Mikaela Åhlin-Kottulinsky to fettle the simulation aspects of R3E such as vehicle physics and tyre modelling. Telemetry data derived from global partners such as
DTM,
WTCC,
ADAC GT Masters and KW Suspensions is also used to further develop the physics model of the cars. The sim was used by the
World Touring Car Cup for their 2020 Esports series due to the season being postponed because of the
COVID-19 pandemic. ==Vehicles==
