Hi!
I'm using vMix with Core i7-10510U processor, 8GB ram, and just using the onboard graphics.
I had a 3 camera setup and it ran fine. One USB camera and two NDI/PTZ cameras. I just got two more NDI cameras, and render time increased significantly.
I found that with 4 cameras it's ok (render time around 20ms), but as soon as I add a 5th it goes up to 70+.
It doesn't matter which camera I remove, it's fine with 4 but not with 5.
All 4 cameras are running 1080p30, and the webcam says 1080p29.97.

Are there any recommendations on how to eek out a little more performance so I can run all 5 cameras?

Thanks

Did you have a fix on this issue? Challenging a relative issue yet no response from anyone and couldn't see this point taking a gander at in google.

@ likewut

Reduce the number of NDI and USB3 Camera Inputs and add a supported Capture Card (HDMI or SDI) to your system as that will help to ease the load on your CPU.
I would also recommend lowering your project settings to 720p (or lower).
