The release of Sol 2.1.3 is a significant update for Assetto Corsa players looking to modernize the game's lighting, weather simulation, and overall visual fidelity. Developed by Peter Boese, Sol is more than just a mod; it is a comprehensive weather engine that transforms the decade-old simulator into a visually competitive experience. What is Sol 2.1.3?

Sol is a dynamic weather simulation system designed specifically for Assetto Corsa. While the original game featured static time and limited weather options, Sol introduces a full 24-hour day/night cycle and complex atmospheric conditions. Version 2.1.3 serves as a refined iteration of the Sol 2.1 framework, focusing on stability, improved cloud rendering, and better integration with the Custom Shaders Patch (CSP). Key Features in Sol 2.1.3 sol 2.1.3 download

This specific update brought several refinements to the sim-racing community:

3D Cloud Positioning: Unlike older versions that used "faked" skybox textures, Sol 2.1.3 utilizes 3D clouds with real positioning and improved lighting/shadows in the game space.

The Sol Planner App: A powerful in-game interface that allows users to create complex weather sequences (e.g., starting a race in the sun and ending in a storm) without manual scripting.

Optimized Performance: This version introduced a redesigned interface between scripts and apps using shared memory, reducing the performance overhead of running a detailed weather sim.

Custom Post-Processing Filters: The download typically includes specialized filters like __Sol and __Sol_Extra that calibrate the game's colors and exposure to match the new lighting model. How to Download and Install Sol 2.1.3

To ensure a clean installation, players should download the mod from official sources like OverTake (formerly RaceDepartment). Prerequisites

Before installing Sol, you must have the following tools set up: Sol | OverTake.gg

If you have an older version of Sol, you must uninstall it first to prevent configuration conflicts.

Download: The official "RAW" files for Sol are typically found on the Sol Overtake.gg (formerly RaceDepartment) page. Uninstall Old Version:

Locate the sol uninstall.bat file inside your downloaded Sol 2.1.3 folder.

Copy and paste this .bat file into your Assetto Corsa root directory. Right-click and select "Run as administrator". Press "Yes" when prompted to delete old config files. 3. Installation Steps

Manual installation is recommended over dragging and dropping into Content Manager to ensure all files reach the correct folders.

Extract Files: Open the Sol 2.1.3 download and find the mods folder.

Copy Folders: Copy the four main folders (typically apps, content, extension, and system).

Paste to AC Root: Paste these folders into your Assetto Corsa root directory (e.g., Steam\steamapps\common\assettocorsa). Confirm and overwrite any existing files. 4. Configuration in Content Manager

Once the files are moved, you must activate the new weather script: Once you’ve completed the sol 2

The sun had set outside, but on my screen, it was always a flat, static noon. I wanted more—I wanted the glare of a low winter sun and the chaos of a midnight rainstorm on the Nordschleife. It was time to install Sol 2.1.3.

The Preparation: I started at Overtake.gg (formerly RaceDepartment) to grab the archive. I knew I couldn't just drag and drop; this required precision. First, I ensured my Custom Shaders Patch (CSP) was updated to at least version 1.76—without it, Sol is just a collection of quiet files.

Cleaning the Slate: Following the official guides, I opened my Assetto Corsa root folder. I found the sol uninstall.bat file from the new download and ran it as an administrator. It’s a nerve-wracking moment, watching the old configs vanish, but it’s the only way to ensure a "clean" sky.

The Installation: I opened the mods folder in the 2.1.3 download and copied the four core folders directly into my game directory. No overwriting occurred—a sign of a perfect "fresh" install.

The Awakening: I launched Content Manager. Under Settings > Custom Shaders Patch > Weather Effects, I selected the "Sol 2.1" weather script. In the game's sidebar, I enabled the "Sol Planner," the magic tool that lets me dictate when the clouds break or the storm begins.

The Result: I loaded into a race at Spa. It started as a clear afternoon, but using the Sol Planner, I accelerated time. I watched the shadows lengthen and the sky turn a deep, bruised purple. As version 2.1.3 took over, the first drops of rain hit the windshield, illuminated by the glow of my dashboard—a complete transformation from the static game I had played just an hour before.

Need help with specific settings?If you're seeing a frame rate drop after the install, try lowering the Reflections Frequency to "Two faces per frame" in the AC settings to regain performance.
