Mumble Overlay is a way to see names of who is talking as an overlay to the game (PR in this case) you are running. Check out
this thread for some more information, as well as an awesome overlay setup.

I absolutely love the new Mumble. This being said, it must be taken into account that there are still people playing on very old machines that are pushed to their limit by PR. Additional applications, even one as small as Mumble, can push these machines too far. I know this to be a fact, as there is a member of my clan that has this very problem.
While it is easy to pop off the standard, "time for an upgrade," type of responses, this is not the attitude that I think should be prevalent within the community. There are multiple factors to consider about that person's real world situation. Having a family to support, being a full time student, paying bills, personal disability, and younger players that have no income are all present in this community in large numbers. The fact that they are playing PR above anything else out there on a machine that can barely run the game is outstanding. These players should be encouraged, not shut out due to a negative attitude in the community because of the quality of their hardware. In some instances, requiring Mumble flatly eliminates a server as a play option for these players, either due to hardware or technical issues.
Speaking of which, technical support for players must be considered. While a player can sometimes find support for Mumble within the community, it can be difficult. I would recommend a new forum section for PRMumble support within the Project Reality Support section. This would give players a more centralized location to seek support, as well as making it easier to locate fixes for common problems, or issues that had already been solved. With the continued integration of PRMumble into PR, I think that this is a necessary step.
