It’s built by βeta, a Discord community that formed in 2021 around the GTA V moviemaking scene, and has been in development since February 2023.

It overhauls the weather system, reworks graphics textures, and adds new features to the game’s own shaders.

Two builds: Legacy for the original game, Enhanced for the ray-traced one. Legacy also runs on FiveM, client and server-side; Enhanced FiveM is in the works.

The base package costs nothing: join the Patreon on its free tier, open the latest update post, and the links are there. Start from Download, bottom right.

Documentation covers install for every platform, Dev Blog tracks what changed, and the Discord icon at bottom left is where support and updates live.
