I have 2 Newtek PTZ1's and one PTZOptics 12X all connected NDI at 1080p60. I have a small 5 port gigabit PoE switch. All IP addresses are static. It seems that at least one camera is way behind the rest (5 seconds) and it tears with motion. I am using a laptop with an 8th gen i7, 16gb of ram, and an SSD. However, when I set everything to 720p all is well. Shouldn't I be able to have 3 cameras at 1080p60 via OBS with no issue?
