This is a guide on how to set up Assetto Corsa.

1. Go to Content Manager's repository and download its ZIP file with the "Latest" tag.
2. Unzip the ZIP file in the download folder.

1. Download Custom Shaders Patch through Content Manager.

2. Click the most recent version to update CSP.

CM initially downloads the recommended CSP version, which is typically outdated. Ignore the flags next to the version numbers, as they are inaccurate for describing CSP version stability. Ask in the CSP Discord server whether a CSP version is suitable for making screenshots.

1. Download Sol through RaceDepartment. Sol supports drag and drop installation with Content Manager. Use Sol "Install Guide" PDF to set up Sol.
2. Go to Sol Discord server and download the "AC Texture Color Corrections" pack in #ac-color-corrections.

For Sol troubleshooting, ask in the Sol Discord server. The Sol Discord server does have experimental versions, which are not released on RaceDepartment. Using an experimental Sol version will not negatively impact filter functionality.

Most filters have support for drag and drop installation with Content Manager. For manual installation, go to Assetto Corsa's Steam file directory (don't use the AC directory in Documents) and drag the following files into their respective location:

└───assettocorsa
    ├───extension
    │   └───weather - # Unzip WFX.ZIP here
    └───system
        └───cfg
            └───ppfilters - # Put filter .INI here
                └───sol_custom_configs - # Put filter .LUA here

1. Press Windows + R
2. Type in %localappdata% and click OK.

└───AppData
    └───Local
        └───AcTools Content Manager
            └───Presets
                ├───Custom Shaders Patch Presets - # Put CSP settings .INI here
                └───Video Settings - # Put video settings .cmpreset here

Tick "Allow free camera," untick "Orbit mode for F5 Camera," and select PNG in "Screenshots format."

"assettocorsa.ini" must be set read-only to prevent CM from reverting its original settings. To do this, follow the steps below:

1. Navigate to \assettocorsa\system\cfg (the game file directory, not the document directory.)
2. Open "assettocorsa.ini"
3. Change the following parameters in the file:

Video presets change Assetto Corsa video settings and CSP presets change Custom Shaders Patch settings. It is recommended to have separate CSP and Video presets for high FPS and high graphics. For optimal filter performance, ask the filter's author for video and CSP presets. Refer to Install Filters and Files for preset installation.

• Avoid FFB excessive clipping
  • Check clipping with an app that displays FFB forces, usually it is the 4th gray bar in a pedals display. The gray bar will turn red once it is filled up, indicating clipping.
  • Ephemeral clipping is OK; i.e., driving over a big dip in a large track.
• Do not use FFBClip app, it is an app made with flawed logic.

• AC FFB settings
  • Turn off all of "Effects" and "Miscellaneous" settings
    • Effects sliders start from a baseline of 100%, which is 0% in the slider. For example, having a slider at 23% would amplify the effect into 123% in total.
• CSP FFB Tweaks:
  • Turn on "More physically accurate gyro implementation."
  • For non-direct-drive wheels, and especially geared wheels, turn on "Range compression assist" in CSP FFB Tweaks.
    • It is recommended to not adjust "Range compression" (default value is 100%).

• Use 50-70% gain to avoid excessive clipping
  • You can set a static baseline of 100% gain instead and then tweak the gain via numpad +/- on a per-car basis.
• FFB post-processing is optional
  • If you do use this option, make your own LUT with WheelCheck. Then convert the output CSV file with Steering Wheel Master, a CSV to LUT processor.

• Use 60-80% gain to avoid excessive clipping
  • You can set a static baseline of 100% gain instead and then tweak the gain via numpad +/- on a per-car basis.
• Belt wheels are near linear in forces, so they have little improvement using FFB post-processing.

• AC FFB settings:

  • FFB gain: (Target sustained steering force / Peak torque = FFB gain)
    • Road cars on average output 6-7 nm during cornering. For example, the formula would follow as so for a 50 nm wheel: 6.5 / 50 = 13.
    • These calculations are not absolute and should be used as a reference point if there was a need for adjustment.

• CSP FFB Tweaks:

  • Turn on output real steering forces to wheel and set the peak torque according to wheel base specification. Do not turn on "Override car setting."

• Wheel Base Software (road car style):

  • 100% Strength/Torque
  • 60-30% Friction (requires adjustment)
  • ~20% Damping
  • 0% inertia
