RS ASIO, a tool that adds ASIO audio driver support to Rocksmith 2014, has been released in version v0.7.5.

RS ASIO patches the game at runtime, replacing virtual WASAPI audio devices with real ASIO devices to enable low-latency audio for guitar and bass interfaces - including on Linux via Proton and WineASIO.

This release fixes an issue where the patcher failed to work on Proton 11 for some versions of the game.
