NDI performance

[Dave Gaming]

Hey guys,

I just installed NDI and wanted to give it a try. Unfortunately the performance is not where I want it to be. I tried out the low latency mode and it gave me a fluent stream for 1080p60 on 1 PC but not higher. 1440p60 is my standard and probably even streaming triple screen would be a wish from my side. In addition to that I would like to stream my content to 2 PCs as I am recording raw gameplay with one pc and streaming my gameplay with another pc. The problem is that the capturing starts stuttering in the recordings whenever I go further than single output 1080p60.

Is there any chance to improve the performance?

I used the most current NewTek NDI version on this homepage and the newest OBS version.

My PC specs are:
Gaming PC
- i9 9900k
- 32GB RAM
- RTX 3090

Streaming PC
- i7 8700k
- 32GB RAM
- RTX 2070 Super

Capturing PC
- i7 8700k
- 32GB RAM
- RTX 2060

Is it probably a problem with the network bandwith?

Thanks in advance <3

Your set-up is too complicated for absolutely no reason, PC 1 has more than enough to do it all if you just stick with 60FPS.

Need higher framerates, try using an app that supports it....

I have a single i7-10700 with a GTX 1660 getting 1080p60 from a NDI PTZ camera. I record and stream from that system (not game play, and overall CPU/GPU load from others source in the 20% range, if that). Recording and streaming on my system barely adds much load. I'm not using Newtek's tools though, and major PTZ vendor has their own Virtual USB drive to receive NDI stream from camera and present as local USB connected video source (so no plug-ins, etc required for OBS). My OS, OBS, and recording are all on a single NVMe SSD. I then move recording off to HDD for archiving afterwards

A single 1080p60 compressed streaming consumes 25-35Mb/s on my 1GbE network. Uncompressed NDI would be over 100Mb/s
