rFactor 2

Vorlage:Unreferenced Vorlage:Infobox video game rFactor 2 is a computer racing simulator developed by the American independent video game and software developer Image Space Incorporated. It is the sequel to the highly acclaimed rFactor. The simulator was released for Windows in 2013. Just like its precursor it's designed to be modded and is used by real professional racing teams, not just for driver training, but also race car development. A lot of its code is derived from rFactor Pro, that's also used by real professional racing and most of the Formula One teams.

rFactor 2 is designed to run any type of four-wheeled vehicle of any era. The simulator features both real life and fictional vehicles and circuits, as well as highly advanced physics, and is highly modifiable. Offline and online racing modes are available.

Development

The public first became aware that the development of rFactor 2 was underway, when Gjon Camaj of Image Space Incorporated posted WIP in-game screenshots on Twitter in early March 2009. Later that month he revealed more details about the upcoming simulator alongside additional in-game screenshots.

In October 2010, Camaj revealed in an extensive interview plans for including licensed content, a new reworked UI, inclusion of dynamic weather, new innovative dynamic racing surface technology, improvements to the AI logic and a new force feedback system with lower input lag and much faster and more direct steering rack forces, along the lines of the popular third party developed “RealFeel” plug-in for rFactor.

Physics

rFactor 2 has received much praise for its highly advanced and accurate simulation of vehicle physics and is the preferred simulator of many real life professional racing teams and car engineers.

The interaction and collaboration between Image Space Incorporated and professional racing teams and their engineers using the ISI developed rFactor Pro platform has benefited the new tire model used in rFactor 2. This has resulted in the “ISI TGM Tyre Tool”, a tool that is also available to third party modders. One unique feature of the new tires is that they visually flex and deform accordingly to the car’s movement and load. Flatspotting and overheating is also simulated with much accuracy. A new tire contact patch model was introduced in April 2015.

rFactor 2 also includes a new constraint system that allows for advanced physics simulation such as chassis flex, which removes the typical infinite rigidity of a virtual vehicle and incorporates unique chassis characteristics into the handling and performance of the car, as well as highly accurate suspension geometry and wheel rates.

Gameplay

The simulator can be played with a wheel, joystick, gamepad or even a keyboard. It includes various controller presets and the possibility of creating a custom controller maps. Driving aids such as traction control, stability control, brake anti-lock, steering help, as well as automatic gear shifting and automatic clutch is available, making the simulator suitable for both experienced and inexperienced players alike.

In a detailed menu the player chooses various options regarding which car to drive (included a tuning menu to choose different specs of that car), which track to race on, how many AI opponents to race against and how fast and aggressive they should be. The menu also gives access to different race session options, such as number of laps/amount of time, time acceleration, Real Road options including rate and presets, flag rules and weather.

When the player loads the track, the chosen car spawns in the garage, with the garage interface available. The player can leave the track and return to the garage at any time during a session by pressing “escape” (ESC). The garage interface features various settings and options. It also features a live race monitor which allows the player to watch the action out on the track.

The car setup interface allows the player to adjust and fine-tune every adjustable part of the car. It also gives out tire temperature and hot pressure readings after a stint has ended.

While in the car, the player has access to a variety of different cameras, both cockpit, hood camera, externally mounted cameras facing in multiple directions, as well as external floating cameras tailing the car. The player can use the “free-look” function to move the point of view using the mouse. There are also multiple groups of TV trackside cameras, as well as a spectator camera function that allows for a free roaming viewpoint all around the track.

The LCD is a part of the HUD. The LCD is divided into multiple sections that the player can toggle between, and shows information about current standings, split gaps, sector times, pit stop options, as well as the mechanical state of the car, such as tire, brake and oil temperatures. Sustained damage is also visually represented in the LCD.

Rules and flags are fully implemented as well. If an incident has occurred, yellow flags are shown, both in the HUD as well as marshals waving them along the track. A green flag is shown as soon as the player leaves the sector in which the incident has occurred. Blue flags are used to signal that a faster car is about to lap another car. Both drive-through and stop/go penalties can be given to players who break the rules, for instance because of a false start. The player can be disqualified if the penalty is not served within the allotted time, which is typically three laps. Full course yellows are also featured in the simulator, with a safety car driving unto the track and collecting the field for a few laps. When the full course yellow is nearly over, the safety cars peels into the pits and releases the field.

Features

Real Road

Real Road is one of the most prominent features of rFactor 2. Rubber is dynamically laid on the track surface, in real time, during a race session by the player and the AI. The rubber can carry over to the next sessions, and this calls for the player to constantly having to adapt to the advancing track conditions during a race weekend, which in a dry race weekend means more and more available grip throughout. The player can choose from various rubber presets to start with, or just choose to start the weekend on a completely green track. Real Road can be accelerated, left at a normal rate or be completely static. The feature also creates grip-affecting marbles outside of the normal racing line.

Real Road also works together with wet weather: when rain hits the track, the previously built-up rubber and marbles is washed away, and the track will then need to be rubbered in again. The wet track surface dries dynamically similar to the aforementioned rubber build-up, due to both cars on track, as well as temperature, sun and wind. The Real Road system of rFactor 2 is unique because it is not scripted but completely dynamic.

Tires

rFactor 2 also features realistic tire wear and damage. This punishes the player for locking up the brakes, because a flatspot will occur, with force feedback vibrations (tire suddenly has edges instead of being perfectly round) and a car imbalance (due to the lost weight of the burnt off tire). Until the tires are changed during a pit stop, the car will feel imbalanced and uncomfortable to drive. Using bad driving techniques will also punish the player, with tires overheating and wearing unevenly. Tire punctures are also featured though not visually represented in-game.

AI

The AI of rFactor 2 is highly advanced and much improved over rFactor. It has spatial awareness, adjustable strength and aggression sliders, and has the ability to “learn” better racing lines around a track, resulting in better lap times. The AI can also be allowed to take control over the player’s car. The player can, by default, race against up to 29 AI in a race.

Other features

Also featured in rFactor 2 is a full day to night cycle with lighting transitions which can be set to real-time or accelerated. Fuel usage, and visual as well as mechanical damage are also featured in the simulator, as well as a “resume from replay” feature where any saved replay can be loaded and the player can then choose to resume driving at any point during that replay.
