Installation

Warning

Catalyst does not work on the alpha branch. This is an issue with BepInEx, not Catalyst.

1. Open the Project Arrhythmia folder.
   • ℹ️ Right-click on Project Arrhythmia in your Steam library > Manage > Browse local files.
2. Download the corresponding version of BepInEx and copy the contents of the archive into the Project Arrhythmia folder:
   • For [21.12.2] (default branch) get BepInEx 6 x64 IL2CPP.
   • For [20.4.4] (legacy branch) get BepInEx 5 x64.
   • ℹ️ If you can't open the archive, try using 7-Zip archiver.
3. Launch Project Arrhythmia once and then close it.
4. In the Project Arrhythmia folder, go to BepInEx > plugins.
   • ℹ️ If you do not see the folder, then you haven't installed BepInEx properly. Try following the previous steps again, or ask for help.
5. Download the corresponding version of Catalyst, and Catalyst.Engine and move them into the plugins folder.
   • For [21.12.2] (default branch) get both AlphaCatalyst.dll, and Catalyst.Engine.dll.
   • For [20.4.4] (legacy branch) get both LegacyCatalyst.dll, and Catalyst.Engine.dll.
6. Catalyst is now installed! Enjoy your boosted framerate.
