I know many of you have been looking for this, and the overlay of Mumble is simply not working with the current client of Star Citizen.
One workaround to this problem is to use a “dummy” process and enforce Mumble to show the overlay. If you use Windowed mode or FullScreen Windowed, you should still be able to see the names. I’m not sure about FullScreen. The downside is that it will display the overlay on your desktop as well, on your web browser, everywhere (it’s like a “layer” added on your screen).

It works for me, hopefully should work for everybody. If you worry about the security of this “dummy” program, you can analyze it. Use it at your own discretion, I do NOT guarantee that it is safe to use it and I haven’t contributed to its creation.
