I'm trying to kill down the render time on our system. We have a 4 camera system, the computer has no inputs on it right now besides two NDI inputs on the same computer and the program that broadcasts them isn't running. Meanwhile, the render time is staying around 72 ms.

System Specs

Windows 10 Pro x64
Core i7-7700K
16 GB Ram
Nvidia Geforce 1080 Ti

4 1080p Camera through SDI capture card
2 NDI inputs through NewBlue Titler Live

Right now as mentioned neither of those are active and the render time is hovering around 72 ms.
I've followed all recommendations on this page: https://www.vmix.com/kno...2/optimising-performance

Have you looked at task manager/services to see what's running in the background?

Is the vMix performance tab is settings showing the nVideo card as the one in use?

I did. It was the only program using the card, besides one or two others. See attached image.

Yes, take a look at this image, I set them earlier. I attached the image to the post.

Every time I see this problem, My goto is to stop the NVidia Share processes (as well as any shadowplay if you are on an older version). If you uninstall nVidia GeForce Experience you essentially do the same thing. Have you looked at that as a possible cause?

EDIT: I see vMix has included this into their official documentation as a fix, sorry if you have done this already. But there are a lot of sneaky background processes that may need another review.

Maybe try killing off each process that's using the GPU systematically and watching the render time?

I did, I figured out which one it was. Thanks. Remote Access didn't look like it was the cause at first, but I killed it and it went down to a 4 ms render time.

Excellent, glad you got it sorted.
