Assetto Corsa Is Obsolete V1163 Is Required Link Link May 2026

Understanding the Issue

Assetto Corsa Version: The game has gone through several updates since its release, and sometimes, mods or additional content require specific versions of the game to work correctly.
v1163 Requirement: This specific version (v1163) might be required for a mod, a piece of DLC (Downloadable Content), or an update that hasn't been integrated into your current game version.

The “Obsolete” Argument (The Bad)

No Native Support: On a fresh Steam install, you are likely on the final “Championship” update. Many modern mods (especially encrypted cars or specific track configs) will crash immediately because they were coded against the v1163 executable.
The UI is a Disaster: Without Content Manager, the stock launcher is unusable. The fact that the community relies on a third-party app to make the game functional proves Kunos has moved on.
Visuals: Even with CSP (Custom Shaders Patch) and Pure, you are polishing a turd. The shadows flicker, the LOD pops, and ray tracing is a hack.

Why Does This Error Still Happen in 2024/2025?

Even though Assetto Corsa was released in 2014, its modding community is more active than ever. Many modders deliberately downgrade their game to v1163 because:

Custom Shaders Patch (CSP) works more reliably with this version.
Rain FX and Lights Patch features were originally optimized for v1163.
Older, beloved car mods (e.g., early RSS or VRC formulas) were compiled against this version’s API.
Some private leagues use a server executable locked to v1163 to prevent cheating.

Thus, if you freshly install Assetto Corsa from Steam in 2025, you will have a version newer than v1163, triggering the error. assetto corsa is obsolete v1163 is required link
