Removing SOL 2.1.3 will not delete user data under /var/lib/sol/ by default. Manually remove that directory if needed.
At 2.1.3, the SOL core daemon reduces heap fragmentation by ~18% compared to 2.1.2. This makes it ideal for resource-constrained environments like edge gateways or virtualized containers with limited RAM.
Upon extraction and preliminary testing, the following observations were noted:
Unlike earlier 2.1.x releases, version 2.1.3 compiles cleanly with GCC 11, Clang 15, and even the experimental LLVM-MinGW toolchain.
Given these enhancements, it’s no wonder the search for “sol 2.1.3 download” spikes among teams modernizing legacy systems.

Sol 2.1.3 is a specific, stable version of the Sol Weather Engine, a foundational mod for Assetto Corsa developed by Peter Boese. While newer versions like Sol 2.2.9 or the successor "Pure" are available, version 2.1.3 remains popular for its balance of performance and compatibility with older Custom Shaders Patch (CSP) versions. How to Download and Install Sol 2.1.3 If you need to roll back or clean your system:
Unlike most Assetto Corsa mods, you cannot install Sol by dragging and dropping it into Content Manager. It requires a manual file transfer to ensure the scripts function correctly.
Source the Files: The official home for Sol is Overtake.gg (formerly RaceDepartment). You will need a free account to download the files.
Clean Uninstall: Before installing 2.1.3, navigate to your Assetto Corsa root directory and run the sol uninstall.bat file from your previous installation to prevent script conflicts. Manual Transfer: Open the downloaded Sol 2.1.3 archive.
Copy the four main folders (apps, content, extension, and system).
Paste them directly into your Assetto Corsa root folder (e.g., steamapps/common/assettocorsa).
Activation: Open Content Manager and go to Settings > Custom Shaders Patch > Weather Effects. Select "Sol 2.1" as your weather script. Key Features of Sol 2.1.3 Removing SOL 2
Version 2.1.3 introduced several refinements to the weather simulation that drastically improved visual fidelity:
3D Cloud Simulation: Clouds were given real positioning in 3D space, meaning they have a 1:1 scale with their shadows and can be physically "reached" by driving.
Sol Planner App: This version matured the Sol Planner, allowing users to create dynamic weather sequences (e.g., a 24-hour cycle) without manual scripting.
New Config System: Introduced a persistent sol_config.ini in your Documents folder, ensuring your custom lighting and exposure settings aren't wiped during updates.
Shared Memory Interface: Improved communication between Python apps and Lua scripts, allowing for real-time parameter updates without resetting the weather engine. System Requirements & Compatibility
Custom Shaders Patch (CSP): Requires CSP version 1.69 or higher for full functionality, though version 1.76 is recommended for the best stability with rain effects.
Hardware Impact: Sol 2.1.3 is highly optimized; however, to maintain FPS, users are advised not to exceed "Two faces per frame" in the reflection frequency settings within Content Manager.
