When i updated my client for teamspeak i got a note saying the overlay for app can be seen as cheating by some games and wanted to see what the stance was for p99. i will not be running it until further info is passed on.
here is the overlay info
Teamspeak 3 Overlay plugin for D3D8, D3D9, D3D10, D3D11 or OpenGL applications.
