Sim racing


Sim racing is the collective term for racing games that attempt to accurately simulate auto racing, complete with real-world variables such as fuel usage, damage, tire wear and grip, and suspension settings. 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. 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 like the Need for Speed series.
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, the experience has become more realistic.
The sim racing gameplay style has been applied in several video games, such as iRacing, Assetto Corsa and Assetto Corsa Competizione, Gran Turismo, Forza Motorsport, and more.

History of sim racing

Arcade simulator era (1982–1989)

Prior to the division between arcade-style racing and sim racing, the earliest attempts at providing driving simulation experiences were arcade racing video games, dating back to Pole Position, a 1982 arcade game developed by Namco, which the game's publisher Atari publicized for its "unbelievable driving realism" in providing a Formula 1 experience behind a racing wheel at the time. It featured other AI cars to race against, crashes caused by collisions with other vehicles and roadside signs, and introduced a qualifying lap concept where the player needs to complete a time trial before they can compete in Grand Prix races. It also pioneered the third-person rear-view perspective used in most racing games since then, with the track's vanishing point swaying side to side as the player approaches corners, accurately simulating forward movement into the distance. In a 2007 retrospective review, Eurogamer called it "a simulation down to the core: those dedicated will eventually reap success but most will be deterred by the difficulty".File:ESports-SimRacing ADAC-Digital-Cup-2019 DAMC05 BMW Z4 GT3.jpg|thumb|Many cars are digitally recreated for sim racing, such as this BMW Z4 GT3 from Assetto Corsa.''Pole Position II was released in 1983 and featured several improvements like giving the player the choice of different race courses. TX-1, developed by Tatsumi in 1983, was licensed to Namco, who in turn licensed it to Atari in America, thus the game is considered a successor to Pole Position II. TX-1, however, placed a greater emphasis on realism, with details such as forcing players to brake or downshift the gear during corners to avoid the risk of losing control, and let go of the accelerator when going into a skid in order to regain control of the steering. It also used force feedback technology, which caused the steering wheel to vibrate, and the game also featured a unique three-screen arcade display for a more three-dimensional perspective of the track. It also introduced nonlinear gameplay by allowing players to choose which path to drive through after each checkpoint, eventually leading to one of eight possible final destinations.
Since the mid-1980s, it became a trend for arcade racing games to use hydraulic motion simulator arcade cabinets. The trend was sparked by Sega's "taikan" games, with "taikan" meaning "body sensation" in Japanese. The "taikan" trend began when Yu Suzuki's team at Sega developed
Hang-On, a racing video game where the player sits on and moves a motorbike replica to control the in-game actions. Hang-On was a popular Grand Prix style rear-view motorbike racer, was considered the first full-body-experience video game, and was regarded as the first motorbike simulator for its realism at the time, in both the handling of the player's motorbike and the AI of the computer-controlled motorcyclists. It used force feedback technology and was also one of the first arcade games to use 16-bit graphics and Sega's "Super Scaler" technology that allowed pseudo-3D sprite-scaling at high frame rates. Suzuki's team at Sega followed it with hydraulic motion simulator cabinets for later racing games, such as Out Run in 1986.
In 1986, Konami released
WEC Le Mans, an early car driving simulator based on the 24 Hours of Le Mans. It attempted to realistically simulate car driving, with the car jumping up and down, turning back and forth, and spinning up to 180 degrees, with an emphasis on acceleration, braking, and gear shifting, along with the need for counter-steering to avoid spin-outs. It also featured a day-night cycle, accurately simulated courses approved by the Automobile Club de l'Ouest, and force feedback to simulate road vibration in the form of a vibrating steering wheel that reacts to the driver's acceleration and off-road bumps. The first racing game with simulation pretensions on a home system is believed to have been Chequered Flag, released by Psion on the 8-bit ZX Spectrum in 1983. REVS, followed in 1986. REVS was a Formula 3 sim that delivered a semi-realistic driving experience by Geoff Crammond that ran on the Commodore 64 and BBC. REVS had a big fan base in England, but not so much in the United States.
3D polygon graphics appeared in arcade racing simulators with Namco's
Winning Run and Atari's Hard Drivin', the latter also becoming a staple on home computers, where it was one of the most widely played simulators up to that point. During the late 1980s to early 1990s, arcade racing games such as Out Run and Virtua Racing had increasingly elaborate, hydraulic motion simulator arcade cabinets, with arcade racers such as Virtua Racing and Daytona USA increasingly focused on simulating the speed and thrills of racing. At the same time, arcade racing games gradually moved away from the more difficult simulation style of Pole Position''. By the early 1990s, arcade racing games had less emphasis on realistic handling or physics, and more emphasis on fast-paced action, speed and thrills.

Emergence of sim racing genre (1989–1997)

Sim racing is generally acknowledged to have really taken off in 1989 with the introduction of Papyrus Design Group's Indianapolis 500: The Simulation, designed by David Kaemmer and Omar Khudari on 16-bit computer hardware. The game is often generally regarded as the personal computer's first true auto racing simulation. Unlike most other racing games at the time, Indianapolis 500 attempted to simulate realistic physics and telemetry, such as its portrayal of the relationship between the four contact patches and the pavement, as well as the loss of grip when making a high-speed turn, forcing the player to adopt a proper racing line and believable throttle-to-brake interaction. It also featured a garage facility to allow players to enact modifications to their vehicle, including adjustments to the tires, shocks and wings. With Indy 500, players could race the full, where even a blowout after would take the player out of the competition. The simulation sold over 200,000 copies. It was around this time that sim racing began distinguishing itself from arcade-style racing. Consoles saw the release of Human Entertainment's Fastest 1 for the Sega Mega Drive/Genesis in 1991. It was considered the most realistic Formula 1 racing simulation up until that time.
In 1991, Namco released the arcade game Mitsubishi Driving Simulator, co-developed with Mitsubishi. It was a serious educational street driving simulator that used 3D polygon technology and a sit-down arcade cabinet to simulate realistic driving, including basics such as ensuring the car is in neutral or parking position, starting the engine, placing the car into gear, releasing the hand-brake, and then driving. The player can choose from three routes while following instructions, avoiding collisions with other vehicles or pedestrians, and waiting at traffic lights; the brakes are accurately simulated, with the car creeping forward after taking the foot off the brake until the hand-brake is applied. Leisure Line magazine considered it the "hit of the show" upon its debut at the 1991 JAMMA show. It was designed for use by Japanese driving schools, with a very expensive cost of AU$150,000 or per unit.
The next major milestone was the 1992 release of Formula One Grand Prix by MicroProse, also developed by Geoff Crammond. This moved the genre along significantly. Multiplayer was made possible by allowing different drivers to take turns, and racers could also hook up their machines for racing via a null modem cable. This only allowed two drivers to race. Leagues emerged where drivers would submit records of their single player races to compare with other drivers. LFRS included 22 two teams consisting of drivers from around the world racing various classes of sim racing in open and restricted setups. Drivers were required to download event specific setup files for each class, to monitor frame rates and apply a checksum to prevent tampering. Drivers saved their race and uploaded to the LFRS server where race results determined overall positions. This is the first sim in which drafting was possible.
Papyrus followed up Indy 500 with IndyCar Racing in 1993 and F1GP was surpassed in all areas. Papyrus later released more tracks and a final expansion included the Indianapolis track plus a paintkit. Now drivers could easily customize their cars. IndyCar Racing sold around 300,000 copies. The first variant of Papyrus' NASCAR Racing series was launched in 1994. In SVGA it pushed the PCs of the time to the limit. Suddenly a resolution of 320×200 seemed a poor option and NASCAR Racing was the race sim of choice for anyone with a capable PC, particularly in North America. It was the first sim where cars no longer looked like boxes. It keyed in on sophisticated physics modeling. NASCAR Racing sold over one million units. Moreover, the first real online racing started with NASCAR Racing using the "Hawaii" dial-in servers and it was not uncommon for these early sim racers to have $300 to $1500 phone bills. Online racing had seen its first true realization, and to many, this was the dawn of "real" sim racing.
1995 saw the release of IndyCar Racing II, updating the first version with the new NASCAR graphics engine. A year later, MicroProse released the successor to F1GP, Grand Prix 2, to much anticipation. GP2 became successful not just because of its detailed and thorough simulation of the 1994 Formula 1 season, but also because it was customizable; this was achievable by way of the online community. Players could change everything about the game: drivers, teams, graphics, physics, car shapes, and eventually even the racetracks. Offline leagues reached their peak with GP2 in 1998.
In 1996, NASCAR Racing 2 was released, further improving the original, and the number of sim racers exploded. The TEN multiplayer hosting service was introduced and went live in November 1997 with the backing of NASCAR and the online sim racing community grew. In 1997, Gran Turismo was released for the PlayStation. It was considered the most realistic racing simulation for consoles at the time, featuring a wealth of meticulous tuning options and an open-ended career mode where players had to undertake driving tests to acquire driving licenses, earn their way into races and choose their own career path. It introduced the racing simulation genre to home consoles, becoming the basis for all modern racing simulations on video game consoles.File:Gran Turismo Screenshot.jpg|thumb|Gameplay from the first Gran Turismo featuring a Mitsubishi FTO GPX
