    1 Is Assetto Corsa worth buying?
    Assetto Corsa (italian for 'race trim') is a full on simulation from the Italy based studio Kunos Simulazioni with proprietary tyre model, licensed sound engine, realistic physics and aerodynamics. The exterior and interior of the cars are fully modeled and the tracks are laserscanned. This game is about driving, experiencing and enjoying a particular car on a particular track - it is more a driving than a racing simulator. With the end of the Early Access program and official release, it has already enough depth to keep drivers occupied for some time and with built in mod-support is continuing to offer diversity in content.
    A proper wheel is strongly recommended to feel the car and the road through the detailed Force Feedback. Also, the game requires at least a good mid ranged PC as of late 2014 for an enjoyable gaming experience.

    2 Basics

    2.1 Format & reinstall

    The game files are primarilly handled through the steam client. Missing files may be reaquired through an 'Check of integrity of game cache' via the steam dropdown menu. Backup your game configuration with your replays, screenshots and setups in username/own documents/assetto corsa, if you'd like format your harddrive or do a clean reinstall.

    2.2 Hardware requirements
    Official hardware requirements (Source):

    Minimum
    OS: Windows Vista, 7, 8, 8.1
    Processor: AMD Athlon X2 2.8 GHZ, Intel Core 2 Duo 2.4 GHZ

    Graphics: DirectX 10.1 (AMD Radeon HD 6450, Nvidia GeForce GT 460)
    DirectX: Version 11
    Network: Broadband Internet connection
    Hard Drive: 15 GB available space
    Sound Card: Integrated

    Recommended
    OS: Windows Vista, 7, 8, 8.1
    Processor: AMD Six-Core CPU, Intel Quad-Core CPU
    Memory: 6 GB RAM
    Graphics: DirectX 11 (AMD Radeon HD 7870, Nvidia GeForce GTX 660)
    DirectX: Version 11
    Network: Broadband Internet connection
    Hard Drive: 30 GB available space
    Sound Card: Integrated

    2.3 Gameperformance characteristics
    This game runs in two primary CPU threads: one for physics, the other one for everything else. It is CPU limited in Singleplayer and GPU limited in Multiplayer. In contrast to many other PC games, Anisotropic Filtering (AF) has a big inpact on FPS. Higher Anti-Aliasing (AA) settings require an increasing amount of GPU memory. Combining AA and FXAA yields the best AA outcome. Raising a single value, AF or AA, may not result in optimal resource management and/or overall high graphical fidelity. Since AF and AA have almost the same impact on FPS, and AA a high impact on GPU memory, a high AF and a low AA setting provide a compromise in FPS, graphical fidelity and resource usage.
    Other settings with a relative high impact on performance are Motion Blur, Depth of Field, Reflection Quality and Reflection Rendering Frequency.
    For more information: click here

    2.4 Supported input devices, presets
    Compatible with keyboard, joystick, pad (mainly 360) and lots of wheels.
    It is strongly recommended to use a wheel with 900° of rotation.

    Presets
    [​IMG]

    'Configuration wizard' for other input devices available.

    2.5 Game development
    Following a regular bi-weekly update cycle in the beginning of 2014, Kunos changed its development schedule to larger updates between longer time periods during the Summer. In mid October 2014, the Release Candidate (RC) was made available to the public. Official release was on the 19.12.14. The game is however still in need of further optimization. Future free content, (paid-) DLC and additional licenses, e.g. RUF, Audi, Toyota, Nissan and Ford have already been announced.

    3 Game Configuration

    3.1 Graphics settings
    3.1.1 Resolution & Rendering mode

    Assetto Corsa will run on Single-, Tripple screens or on the Oculus Rift VR device. Many resolutions in combination with many refresh rate options (Hz) from 640x480 @ 25Hz to 1920x1080 @60Hz or resolutions for tripple screens are available.

    3.1.2 Anti Aliasing & Anisotropic Filtering
    As both main graphical quality options, AA and AF should be looked at first when balancing fidelity and performance. Note that AF requires more resources in AC in comparision with other games.

    3.1.3 Reflection Quality & Reflection Rendering Frequency
    Both these settings are responsible for the reflection quality on the car's bodywork. Reflection Quality determines the resolution of the reflection and Rendering Frequency dictates how often reflections on the bodywork will be updated.

    3.1.4 Shadow resolution, World detail and Smoke generation
    Lowering Shadow resolution and World detail can help increase FPS on parts of tracks with a lot of detail or many trees that are casting shadows - especially helpful on mod tracks. Lowering Smoke generation helps to reduce the FPS drop during race starts.

    3.1.5 Post processing effects (PPEs)
    [​IMG]

    PPEs have an impact on FPS, Motion blur and Depth of field quality more so than the rest. The headlights of the car won't glow with PPEs or Glare quality disabled and have a deminished glow with Glare quality reduced. You may reduce Color saturation below 100%, or set the PPE preset to 'Photogenic' in order to bring the game visuals closer to reality. Enabling Fast Approximate Anti Aliasing (FAAA) simultaniously with normal AA will reduce FPS greatly. FAAA is not as effective as AA.

    3.1.6 Vsync
    Vsync attempts to synchronise the FPS with your monitor's refresh rate and may smoothen the picture. If your FPS are overall lower than your monitor's refresh rate, Vsync won't improve picture quality and is better to turn off. Take care not to have a FPS multiplyer of 1x, 1,2x, 1,25x, 1,33x or 1,5x of your monitor's refresh rate to avoid teering. E.g. for 60Hz that'll be 60, 72, 80 or 90 FPS. Check your frame rate limit setting as well. More information about that click here.

    3.1.7 Maximum frame latency
    To be changed in 'Steam/steamapps/common/assetto corsa/system/cfg/graphics ini'. Setting of how many frames the game should render the frames in advance, to what you are seeing on screen. Default value is 0. A value of 1 may improve picture quality and Force Feedback (FFB) response. Higher values will desynchronise game imputs with the visuals. More information on that click here.

    3.1.8 Mirror resolution & High quality mirror reflection
    Quality of mirror reflections - has a minor impact on FPS and should be fully enabled.

    3.2 Field of View (FoV)
    The Field of View (FoV) ingame should mimic your FoV sitting in a car in reality. Correct FoV is important for proper (sim-) racing & gaming and to experience a proper sense of speed while driving. Although there has been no official word if this game uses vertical or horizontal FOV, experimental results showed that AC features vertical FOV.

    3.3 How to disable vertical head movement?
    Tick the option in the view tab for 'Lock onboard camera to horizon'.

    3.4 Glancing left/right speed
    Determines the speed at which you glance left or right during driving. This option is subjective, but an increase does help to reduce the time you are looking away from the road while driving.

    3.6 Input device configuration
    3.6.1 Keyboard

    Assign buttons and there you go.

    3.6.2 Gamepad
    No information available at this time.

    3.6.3 Joystick
    No information available at this time.

    3.6.4 Wheel, Pedals & Shifter
    You may look for specific Wheels & pedals click here.

    3.6.4.1 Degrees of rotation
    Determines the sensitivity of the steering wheel. If the the maximum rotation is matched with your wheel's rotation, both your and the ingame wheel will rotate congruently. You may increase them to the maximum (1180°), in order to reduce sensitivity and therefore increase steering precision of Formula cars.

    3.6.4.2 Throttle, brake and clutch boundaries
    You may adjust pedal bounderies with the white sliders. The top brake boundary my be changed, in order to reduce the necessary force required to press your Load Cell brake pedal and still retain 100% maximum brake ingame.

    3.6.4.3 Gear shift debouncing
    Adjust slider to eliminate skipping gears while shifting.

    3.6.4.4 KERS & DRS activation
    As options available, however both are not yet implemented as activatable features in the game. These are expected with the addition of the McLaren P1. Albeit the Hi-KERS system of the LaFerrari is fully modeled.

    3.6.4.5 Steering settings
    Recommended to reduce all options to minimum other than FFB gain, in order to experience the purest FFB possible. You may choose a Filter value of 1 or 2% to reduce a sudden jiggle of the wheel while driving due to road surface imperfections.

    3.6.4.6 Brake gamma
    A linear brake gamma (value of 1.00) is highly recommended to have a predictable and precise braking feel.
    For Load Cell users: the human foot with its plethora of pressure sensors is able to detect and react to pressure a lot better than to foot travel. A linear brake gamma and a linear pressure increase of the Load Cell will benefit greatly from that.

    3.6.5 Save configuration feature
    You may save any configuration of your input devices via this feature. You may have to double click on an entry multiple times for it to load properly. You also may save a general profile each for Street-, GT- and Formula cars.

    3.7 Audio balance
    You may adjust sound levels in the Audio options menu.

    4.1 Hud & apps
    4.1.1 In general & dev mode activiation

    You are free to move the ingame apps to anywhere on the screen you like. Even to a different screen, if you have a tripple setup. They can be fixed in place by clicking the pin in the top right. You have the choice from a multitude of apps that display a variety of information. Exactly how much and how detailed that info should be, is up to you.

    Activate dev mode to enable access to more apps by going to
    SteamApps\common\assettocorsa\system\cfg and open the assetto_corsa.ini
    and changing
    ENABLE_DEV_APPS=0
    from 0 to 1.

    FPS, FT, CPU & OCC are dependant on your hardware, rest of the values should be independant., DIP & B.Size affect GPU & Vram. OCC is indicator of physics thread load. TRI is track dependant.
    DIP range 600 - 1300
    B.Size range 1000 - 1800
    OCC range 1.9 - 2.7, can go up to 3.6

    Aerodynamics
    1)
    [​IMG]
    Left to right/top to bottom: front wing, bodywork, rear wing, diffuser. Does not provide values during replay.

    2)
    [​IMG]
    Live values during driving, including aero balance, overall downforce and drag in kg. Useful for analysis of aerodynamics.
    In yellow:
    AOA: Angle of attack
    GH: Ground height (absolute value)
    CD: drag coefficient
    CL: lift coefficient - positive is downforce, negative is lift
    In white:
    FRH: front ride height delta
    RRH: rear ride height delta
    (ride height changes, when the suspension is compressed by aerodynamic downforce)

    Suspension
    1)
    [​IMG]
    Very useful app for analysis of tyre temperatures, suspension load and grip levels.
    Yellow bars in the top/middle - load meter per tyre. Turns red, if tyre looses traction. Big blue/magenta rectangles in the middle - overall and partial visualisation of tyre temperatures with three temps per tyre, pressure display in psi. Partial temperature spike during lock up visible. Valid only live, not during replay. Corners: tyre orientation (C= live camber values).

    2)
    [​IMG]
    Load meter accurate during replay.

    3)
    [​IMG]
    Fine visualisation of the movement of the double wishbone suspension (yellow lines). Very useful for suspension travel analysis. Works during replays. Toggle backspace to enable/disable yellow lines.
    (recommended for analysis)

    4.2 Assists & ABS
    Traction Control (TC), Stability Control (SC) and ABS can be adjusted in the driving options. The levels of TC and ABS can be chosen on the fly during driving by CTRL+T or CTRL+A respectively. A high value for TC is less restrictive and intrusive than a low one. Formula cars don't feature ABS and not all street or GT cars have ABS or TC. If you enable Pro settings in the driving options, all gaming aids mirror the aids of that particular car in reality.

    4.3 Ambient & track temperature
    Default value is 26°C for ambient and 32°C for track temperature. These are used for Pro settings and serve as a benchmark for competitive hotlap times. More ambient temperature raises the track temperature as well, which yields more grip and thus faster lap times. Multiplayer servers always use the default value.

    4.4 Replays
    Go to 'documents/assettocorsa/replay' - look for a file named 'cr' - rename it - restart the game.
    This 'cr' file only contains the replay of the most recent session, either SP or MP. Rename it before going into another session, if you want to keep it.
    You can create a hotlink on your desktop or anywhere convenient to advance to the replay directory quickly.
    (subsection courtesy of @Chris Stacey )

    You can save only a selection of the replay by sliding the two green corner markers to the designated beginning and end.

    4.5 Grip levels / Track surface
    These are all ingame available presets with their numerical values. (Source)

    Optimum
    Session Start: 100
    Ramdomness:
    Lap Gain:1

    Fast
    Session Start: 97
    Ramdomness: 20
    Lap Gain: 20

    Green
    Session Start: 92
    Ramdomness: 20
    Lap Gain: 10

    Slow
    Session Start: 94
    Ramdomness: 15
    Lap Gain: 60

    Old
    Session Start: 86
    Ramdomness: 30
    Lap Gain: 50

    Dust
    Session Start: 83
    Ramdomness: 10
    Lap Gain: 18

    Explaination of Randomness value from the official AC forums (Source)
    "Randomness adds or subtracts a percentage to the starting grip.

    Example for the "old" preset:
    Session Start: 86
    Ramdomness: 30

    Means that the starting grip is 86%, but with a random margin of +/- 3%. Think that even 1% difference is CLEARLY noticeable while driving."


    Lap Gain
    Value of number of laps per car to add 1% grip.

    Grip values and a 'Transfer_grip' value can be individually set in the server_cfg.ini in a dedicated server client. See section 8 Dedicated Server configuration for more information.

    4.6 Fuel
    (only with enabled fuel consumption)
    The estimated laps for the current fuel load in the car setup options can only be calculated after a full lap has been completed. This estimation will gain accuracy with more laps driven in the same sitting.
    Calculated by (rpm*gas*CONSUMPTION)/1000 litres
    E.g. 'CONSUMPTION=0.00165'

    4.7 Comparison of lap times
    4.7.1 Ingame telemetry

    [​IMG]
    No information will be displayed if you haven't driven the current combination. You'll see red lines representing your fastest lap. You'll see white lines after you've driven at least one complete lap afterwards - they always represent your last full lap. A higher white line than the red one means you applied more throttle, brake, you were in a higher gear or were faster (speed). You can compare values by hovering over them with the mouse.
    Remember this plot is normalized to distance, not time or speed. More time could've been gained or lost in slower sections of the track, than on fast straights.

    4.7.2 Third party apps (telemetry)

    4.8 Car setups
    Look to our Setup forum - click here
    or to the Setup Guide of yours truly - click here

    4.9 Converting a Qually into a Race setup
    In the majority of cases you have to change the tyres to the fastest available, reduce the fuel load to a minimum (2 or 3 laps including an outlap) and either adjust the aerodynamics, the braking differential (diff coast) or the acceleration differential (diff power) to counteract potential over- or understeer that manifests itself only in Qualifying trim. More extensive setup adjustments may be required on a case by case basis.

    4.11 Multiplayer
    4.11.1 Server filters


    [​IMG]
    From left to right: pickup mode, empty servers, full servers, password protected servers, servers only in booking mode, display servers you joined recently (doesn't work as of 16.08.14), search window

    4.11.2 Booking & pickup mode
    Booking mode
    You have to book within the aloted time. After doing so successfully, you can close the game or even shut down your computer and join the server later. This mode fits Club or League races well.

    Pickup mode
    Cars and their skins are prebooked. Just pick an available car and join the session currently in progress. Similar to drop in / drop out Co-op.

    5 Modding
    5.1 In general

    Assetto Corsa is highly modable - from the app language python to the available modding tools (SDK) for cars, tracks & the career mode. Pay heed to restart the game after installing mods of any kind for them to be visible.



    5.2 Cars
    RD resources - click here
    Install location - (steamapps folder) - assetto corsa/content/cars

    Be aware that building a car takes a lot of time & effort - many custom cars are still in development, their looks and physics are subject to change.

    5.3 Car skins
    RD resources - click here
    Install locations - (steamapps folder) - assetto corsa/content/cars/(select a car)/skins
    RD skin collection - click here

    5.4 Tracks
    RD resources - click here
    Install location - (steamapps folder) - assetto corsa/content/tracks

    Many mod tracks are not as optimized as the ones from Kunos, they will induce more CPU load. How much, varies on a case by case basis.

    5.5 Career
    RD resources - click here
    Install location - (steamapps folder) - assetto corsa/content/career

    5.6 Identifying track versions
    Some tracks don't contain a readme file or their version number can't be easily discerned. One way to do that, is to look up the date of last modification of the .kn5 file for the track.

    5.7 Custom Apps
    RD ressources - click here
    Install location - (steamapps folder) - assetto corsa/apps/python

    Activate them like the Kunos' apps first from the config menu and in game from the right sidebar during driving.

    6 The RACEDEPARTMENT Assetto Corsa Racing Club
    6.1 In general

    Our Racing Clubs, including the Assetto Corsa one, are casual events, where a driver's classification and lap times don't really matter. What matters is to have a good racing experience in a controlled environment, that is to drive on a password protected dedicated server and to have clear racing rules that everybody has to adhere to. Drivers are expected to avoid L1/T1 incidents, unnecessary contact, pay heed to blue flags and giving each other room to maneuver on the track.

    6.2 Mechanics
    6.2.1 Event threads

    US, EU and AUstralian events are posted here. Their organizers post them several days or a week in advance to give potential participants plenty of time to adjust their schedule and do some practice, if they wish. Further, the organizers take care to provide clear rules for that specific event or general rules inherent to their region or to the organizer itself. Please read them carefully - you automaticaly agree to them, if you sign up for a particular event.
    In general, you are free to participate in events in any region. Please refrain to mention lap times in the event threads - people may get discouraged by seeing them and comparing them to their own, hence creating a perception of competition, that is not in the vein of a Racing Club.

    6.2.2 Racing license
    To be eligible to participate, you first have to apply for a license - do so here.

    6.2.3 Sign up & sign out
    You sign up by writing a clear "sign me up" message in the event thread. Beware of the time till no further sign ups will be accepted, if there is one. If you do need to sign out, please do so in time as well. Further details are provided in the particular event thread.

    6.2.4 Premium
    Here at RACEDEPARTMENT, a voluntary premium membership is available. For 10€ or your regional equivalent per anno, you help us to pay for our site and our server traffic. In doing so, you'll gain many benefits, including but not limited to, priority sign ups for our events, a driving school lession (see 7 The RACEDEPARTMENT Driver Academy Program for Premium Members), access to a special forum area 'the paddock club' and many more.
    For more information - click here.

    6.2.5 Servers
    Most RD servers are located in the Netherlands. EU events take place on server #2. We also have a 24/7 server - for more information - click here.

    6.2.6 Booking & Pickup mode
    Most events feature booking mode, some the pickup mode. For more details, please read the particular event thread.

    6.2.7 Teamspeak
    It is strongly encouraged to be present in teamspeak or even mandatory for many events. Doing so, serves a multitude of objectives: a place to be on the same page during the event, to pick up important information, to pass a lapping situation savely, to simply converse with one another and to build a sense of community.
    Password and login details - click here (only accessible for licensed members).

    6.2.8 After the race
    You are free to share your event experience in the corresponding thread afterwards. If you have a disagreement with another driver or want to clear an incident, please do that via PM first - if you are still not satisfied, you can write and submit a report about it to the event organizer or to a staff member.
    For more information about incidents and proper incident reporting - click here.

    9 Errors and Troubleshooting
    9.1 Game erros

    • Many issues are discussed in section 10 below as well.
    • 'the server will shutdown' in loading screen - make sure to type in the right password for the server.
    • 'no text in loading screen', assettoCorsa.exe will freeze - exit fraps or any other flash program.
    • 'Missing content', 'file errors' - run a 'check integrity of game cache' via steam context menu.
    • Certain cars won't load - choose an existing Kunos car & track first - more info click here
    • 'No car, only driver displayed' - LOD issue (work around courtesy of @Chris Partridge )
      Go into \SteamLibrary\SteamApps\common\assettocorsa\content\cars\urd_egt_ferruccio\data and open up LODS.ini with notepad.

      Find FILE=urd_egt_ferruccio.kn5
      IN=0
      OUT=50

      And make OUT=500, try 5000 if doesn't work
    9.2 95% CPU Warning
    Your CPU is at peak load. The exact number of CPU load may not be accurate. The load indicators of the Windows Task Manager are not necessary correct - 100% CPU load is only accomplished by benchmark software like PRIME 95.
    The AI is only calculated on one dedicated CPU core, try reducing grid size or overclock your CPU (if you decide to). Also, Assetto Corsa scales with raw clockspeed very well. Beware that overclocking your hardware components may viod their warranty. Many mod tracks are not as optimized as Kunos' tracks and may require more CPU performance. AMD CPUs seem to be more prone to this issue than Intel's ones.
    For more information - click here.

    9.3 No tracks available
    May be caused by specific mod tracks or spelling and/or punctuation errors in the 'ui_track.json' file.
    For more information - click here.

    9.4 Hardware issues
    • Wheel/Pedal issues - look through our dedicated (sim-) hardware forum click here or open up a thread there and ask.
    9.5 G27 rumble
    Look first in the appropriate wheel settings thread.
    Mainly a construction issue with gear driven wheels. You may first reduce the Kerb effects & Road Effects sliders. This effect may vary from individual wheel to wheel.
    Information on the construction issue and a possible remedy - click here.
    For more information - click here.

    9.6 Stutter
    May be caused by long log files and general performance requirements of custom apps, like the F1 Hud app by FCM. Remove custom apps to remedy this issue.
    For more information 1 - click here.
    For more information 2 - click here.

    9.7 Ride height calculation

    [​IMG]

    Red = invalid
    Yellow = may work or may not
    White = valid

    Values affecting ride height are: spring rate, tyre pressure, ride height setting. Different cars may have own minimum ride height requirements. Adjust in the setup menu as needed.
