Mumble in-game Overlay Documentation

Mumble overlay screenshot

Mumble can show information within rendered applications; most notably videogames which are typically used with full screen rendering.

Mumble can show connected and/or talking voice participants as well as current FPS and/or the clock time.

The overlay can give users feedback about who is connected or who is talking when the application would otherwise obscure this information. Even if the user has Mumble open on a second monitor, the overlay may be a useful addition as it can be placed freely on the primarily focused on monitor.

Mumble hooks into 3D rendering technology. On Windows it currently supports Direct3D 9/10/11 and OpenGL. On Linux and macOS it supports OpenGL. Both 32- and 64-bit applications are supported.
