For Linux/MacOS Users

To use this mod on Linux/MacOS x86_64 or arm64, you need to download from Actions.

Since the Nvidia AFX SDK client only supports Windows, smart mode of noise-canceling is not available on Linux or macOS. If you do need this functionality, you may modify NvidiaInit.java yourself. For more information, see the Nvidia User Guide.

Due to limited resources, only partial support is provided for Linux. MacOS is not actively supported.
