I'm having no luck getting the OSD to work with Lockheed Martin's Prepar3D V4.4. This "used" to work but seems to be non functional now. I've tried all these options: Application Detection Level: Low, Medium, High Stealth Mode: On/Off On-Screen Display Support: On/Of On-Screen Display Rendering mode: Vector 2D, Vector 3D, Raster 3D On-Screen Display coordinate space: ViewPort, Framebuffer On-Screen Display Shadow: On/Off What I do get is the OSD shows up in P3D "aircraft preview" screen and will show up when loading, but as soon as I get into the main flight screen, nothing shows. nVidia drivers are 417.22. Any suggestions or am I just out of luck? Cheers, Rob.
