Hi there! I've tried setting up a NDI between my streaming and gaming PCs, but I'm facing some lag issues. I'm attempting to record and stream at 1080p60, yet people suggest needing over 100Mbps between both machines. My network is currently maxing out at 130Mbps according to Task Manager, even though speed tests show 500Mbps download and upload with 1Gbps connections using Cat 5e and Cat 6 cables. I'm aiming for speeds above 200Mbps to support recording and streaming. I've attached a diagram of my setup. Are my network switches limiting performance? I'm new to this and mostly plug-and-play, so any advice would be super helpful! Thanks!

Execute iperf across the machines. Occasionally I think it's not a network problem, but an issue with ndi's data transmission. Are there interruptions in the stream? What precise problem are you encountering?

You're facing a network bottleneck. Currently, your speed is only 100mbs on Task Manager, which isn't enough for smooth 1080p at 60fps. I'm running Iperf to check the actual throughput and will share the findings. *EDIT* After testing, the transfer was about 1GB at 935Mbits—still below your target.
