# How to Enable CSP Server Features in Assetto Corsa

> Take advantage of rain FX, night lighting, and advanced physics. Learn how to enable Custom Shaders Patch (CSP) features on your Assetto Corsa server.

## Beyond the Vanilla Engine

The Custom Shaders Patch (CSP) has transformed Assetto Corsa into a modern, industry-leading simulation platform. It adds support for dynamic rain FX, localized night lighting, and optimized networked physics that are not present in the base game. To use these features in a multiplayer environment, your server must be correctly configured to broadcast this specialized data to connected clients.

## Server-Side Activation

If you are using the Content Manager server wrapper (highly recommended for modern servers), you can enable and customize CSP features within the `extra_cfg.yml` file.

<Steps>
  <Step title="Locate extra_cfg.yml">
    In your [Game Panel](https://panel.freakhosting.com) File Manager, navigate to your server's configuration directory and open `extra_cfg.yml`.
  </Step>

  <Step title="Enable Rain FX">
    Find the `RAIN_FX` property and set it to `1`. This allows the server to synchronize weather states and rainfall intensity across all drivers.
  </Step>

  <Step title="Enable Admin GUI">
    Set `ALLOW_GUI_CONSOLE` to `1`. This provides an in-game administrative overlay for authenticated admins, allowing for real-time session management.
  </Step>
</Steps>

## Technical Requirements for Drivers

While the server can "broadcast" CSP features, the final visual output is rendered locally on each player's computer.

<Tabs>
  <Tab title="Driver Requirements">
    Every player **must** have the Custom Shaders Patch (and preferably Sol or Pure) installed locally via Content Manager.
  </Tab>

  <Tab title="Incompatibility Issues">
    Players attempting to drive in rainy or night-time conditions without CSP will experience severe visual glitches, such as solid black skies or missing textures, and their game may crash during session transitions.
  </Tab>
</Tabs>

<Important>
  ### Realism vs. Performance

  Enabling high-fidelity CSP features like `Physics Tweaks` or `Extended Physics` can increase the server's CPU load. We recommend testing these features with a small group of drivers before hosting a full 32-player grid.
