GOverlay, a graphical tool for managing Linux gaming overlays, has been released in version 1.9.3.

Shortly after version 1.9.2, the update brings native ReShade support, 3D color LUTs for vkBasalt and a new ray tracing benchmark in PasCube. Global settings can now be cloned into game profiles, and the EnvVars section is now called Tweaks and also supports launch arguments.
