Problems running single-host nDisplay

What’s the problem?

The problem is that I have a remote control web interface and a camera set up in the Unreal Editor, and everything runs smoothly when playing it in the Editor. But when I run it in nDisplay using SwitchBoard, I don’t have performance at all and the camera is not moving when using the web interface.

Setup

I have Unreal Engine running on my laptop and want to test nDisplay on my laptop and a external monitor. I’m using the built-in NodeJS based web interface and I made a exploding rock to test the realtime-performance.

My tests

I’ve tested running nDisplay using Switchboard and the screen mapping is fine. Now I don’t have a camera tracker to link with LiveLink (yet) so I wanna test it by moving the camera manually, so I thought of using the remote control web interface to do the job, but as you’ve already read, that’s not working. I also played around with a exploding rock (which I made by blueprints) and it’s exploding in normal speed in the editor. However, if I run nDisplay, the explosion happens five to ten seconds later than it should do and the explosion lags a lot (like literally all the performance is gone).

Any solutions?

I feel like nDisplay still lacks some sort of guide and I hope that going to be fixed in the future. Anyways, any help would be appreciated. Thanks in advance!

I might be doing things wrong as I’m just a beginner at this, but I haven’t gotten Web Remote to work by itself over nDisplay. What I did to make it work was have nDisplay start and join a multi-user-server and then join that server with the editor. The editor makes the Web Remote work, so if the editor is active in the Multi User, the remote works.
Can’t help with your performance, struggling with that myself.
(Also Multi User on the same laptop as your nDisplay node will cut your performance even more)
