I have got a similar Application to “Teamspeak Voice Overlay” and “Voice Overlay” to work with ArmA without any noticeable drop in frame rate. The App is called “TSDisp”. TSDisp is pretty basic, but functional. It displays the speaker, and channel if required.

Until a “fix” for TSOL or Voice Overlay comes out, this is my compromise. At least I can see who is transmitting in the Teamspeak channel now without it impacting the game.

For some reason, I couldn’t get this Application to display over the game window when I started the game normally. Instead, I have to run ArmA in its own Window. (Done via the ArmA Launcher v1.1 – link below).

Instructions as follows:

1. Have a read about TSDisp, and download: Here
2. Install ArmA Launcher v1.1 (this is an easy way of running ArmA windowed, as it is selectable from the Options Menu). Download: Here
3. Go to C:\Documents and Settings\My Documents\ArmA and make a backup of the ArmA.cfg file, and save it somewhere safe (just in case).
4. Once that’s done. Open the ArmA.cfg file in Notepad, and adjust the following settings (I use a Wide screen Monitor so my settings might not be good for your set up. You might have to play about with the settings to get the game window to your liking). If running a 4:3 monitor, you might not have to change anything - bonus!
5. winX=0;
6. winY=30;
7. winW=1500;
8. winH=890;
9. winDefW=1280;
10. winDefH=960;
11. This puts the game window across my monitor screen, with a couple of millimetre gaps at the top and bottom .
12. Finally to get the Taskbar out of the way (if desired): Right Click the Taskbar > Select Properties > and tick Auto Hide the Taskbar

TSDisp displays the speaker now, without a drop in FPS (which was happening in TS Overlay, and Voice Overlay - for me).

This solution might not be everybody’s cup of tea. But for me at least, it works in the interim. If it helps a fellow TG’r out, then so much the better.
