Are you using render window on your client (I assume you are in MSFS)? I have a server pc getting 80 fps with 3 monitors.
The client is also getting 80 fps with MSFS and a monitor and 3 32" insignia tvs.
I haven’t tried WidevieW yet but assume if the client is running MSFS with the aircraft rendered on three windows (left, center, right, infront of the windshield), WidevieW and Traffic will drive the client as shown in your video.
If you use a different technique in your client, please let me know?
