Do you actually talk to ATC with that, and get a reply?
Yes
Also, why won't the native Windows 10 VR work?
I have no idea. What happens when you try?
What you have to understand is VR has nothing to do with PF3. Basically all a VR program does is listen to your commands and sends the relevant configured hotkey to PF3. As far as PF3 is concerned you are simply using hotkeys and it knows nothing about voice commands. That's how VR works in a nutshell. I don't use it myself, never have, but PF3 works with VR programs and I have not heard about any that do not work with PF3.
Any chance that might work in the future?
If it doesn't work with PF3 it has nothing to do with our program and it's the VR program itself.
