Having trouble with NDI on a Dell G16 7630 laptop. 32GB Ram, RTX4070, i9-13900HX. The 2.5G Killer E3100g may be the issue but after lots of testing I'm not sure. In tests, 1 single 1080p 50fps NDI stream seems to struggle through it. I have tested both streaming out and capturing in and the issue is the same. Laggy video and audio dropouts. I have tried pretty much every solution available (including disabling the Killer Network Sevice software - which appears to be a known problem - and reducing the Speed & Duplex to 1Gbps which was another suggestion) Nvidia drivers are up to date and all the relevant tweaks done in the Nvidia software as far as I can see. I am about to chuck this beast through a window in frustration. I have 3 older PCs with much lower specs which all handle NDI perfectly on my network. I bought a 1Gbps USBC adapter which initially seemed better but now has the same issues. Wifi is no better either (my Macbook pro handles NDI perfectly well on Wi-fi) So there is clearly a problem specific to this Dell laptop. Dell are no help as it is apparently not a hardware issue and Internet speeds are absolutely fine, its just NDI that struggles.

Is the lag in just vMix? What about NDI Studio Monitor? Also, you don't mention if this is NDI HX or full NDI.
