Hello,

I want to have a simple ndisplay setup, to run locally such that the output is a stereo side by side image. I made the config with one node, one viewport and it has just the default view origin.

Via switchboard, I can run this and sure it opens up in side by side mode, but its INCREDIBLY slow. I literally have just a cube in the scene.

Also, any functionality that i added in the event graph of the ndisplay config, such as moving the view origin based on arrow keys does not work. it is simply stuck there.

I even tried running a packaged build using these docs. Same result and again, incredibly slow.

Any help or guidance for any step of this process would be great.

Thanks in advance!

I’d recommend looking at Unreal Insights to see why it is so slow.

Regarding the arrow keys, check your logs and see if the correct DCRA Asset is spawned/referenced, or if it spawns a new/default one without the functionality in the blueprint.

Stage Monitor should give you some insight on at least which thread is being taxed.
