Assetto Corsa Modding on OpenMods

A racing sim where mods substantially outproduce the base game

Assetto Corsa (2014) is Kunos Simulazioni's racing simulator and one of the most-modded racing games in PC history. The base game ships with a respectable but limited car and track list; the community has produced thousands of additional cars, hundreds of tracks (real-world circuits and fictional courses), and most importantly Custom Shaders Patch (CSP), a community-built graphics and physics extension that transforms what the engine can do.

The pairing of CSP + Content Manager (a community-built launcher and mod manager) is the de-facto Assetto Corsa modding stack. Many serious sim racers run AC mostly for mod content rather than vanilla content.

The toolchain

• Content Manager (CM): community-built launcher and mod manager. Replaces Kunos's official launcher entirely. Free tier covers most users; Patreon "full" version unlocks additional features.
• Custom Shaders Patch (CSP): graphics and physics extension by x4fab and contributors. Adds modern lighting, weather, rain physics, day-night cycles to AC.
• Sol: companion weather and lighting overhaul, built on CSP.
• Pure: alternative to Sol with different visual philosophy.

What you'll find on OpenMods

AC mods live primarily on community sites: RaceDepartment, AssettoLand, Overtake.gg. GitHub hosts source for CSP and Content Manager themselves. OpenMods catalogues GitHub-published AC mods.

Practical notes

• Don't use Kunos's official launcher for modded play. Content Manager handles mod management, server browsing, and CSP/Sol/Pure configuration far better. Most modded AC users only launch through CM.
• CSP is layered. Base CSP, then Sol (or Pure) on top, then individual track and car CSP extensions. The dependency chain takes setup time but is well-documented in the AC modding wiki.
• Quality of car and track mods varies enormously. Some are professional-tier (replicating real cars in detail). Others are crude. Read RaceDepartment reviews before installing.
• Multiplayer requires identical mod sets. Public AC servers run specific mod combinations; joining one requires matching the server's content.
