Game Ownership

Vintage Story is developed and published by Anego Studios. All game assets, textures, sounds, models, and the original client binaries are the intellectual property of Anego Studios. Optimum does not distribute, bundle, or claim ownership of these files.

How Distribution Works

Optimum distributes no game files. The release is source only: the performance patches and the Optimum source files, under GPL-3.0 + Commons Clause. It contains no game assets, no prebuilt binaries, and none of the official client code.

When you build, the scripts download the official client directly from Anego Studios' CDN (cdn.vintagestory.at) onto your machine, reconstruct the engine source there, apply the Optimum patches, and produce a ready-to-run client locally. The game assets, the runtime, and the resulting DLLs all stay on your machine. They are never redistributed by Optimum.

What Optimum Owns

Optimum's original contribution is the set of performance patches applied to the decompiled source, the optimized shader replacements, the build infrastructure, and the launcher branding. These files live in the sources/, patches/, and scripts/ directories of the repository.

What Optimum Does Not Own

  • Game assets (textures, models, sounds, JSON block/item definitions)
  • The original unmodified client binaries
  • The Vintage Story name and logo (used only for compatibility identification)

License Interaction

Optimum's GPL-3.0 + Commons Clause applies to Optimum's source code and patches. It does not extend to or override Anego Studios' rights over Vintage Story itself. Users must own a valid Vintage Story license to play. Optimum does not bypass, circumvent, or modify the game's account authentication.

A Valid License is Required

Optimum requires a legitimate Vintage Story account. The client authenticates with Anego Studios' servers on launch, the same as vanilla. There is no offline mode, no license crack, no authentication bypass.
