I have 3 pc for Game Streaming i have one 3060 Gpu pc for Main production, Two 1660 Gpu Pc for Spectating and NDI Output, I will Collect Data from Two Spectating Pc to Main production PC through NDI Screen Capture or Screen Capture HX,

But My Problem is When i am Conneting Two Spectate pc in NDI Screen Capture its Getting Lagging in one Feed, If i Connect one pc on NDI Screen Capture and Another One in NDI Screen Capture HX i works Fine. I need Sollution for This,

How can i Use only one Capture? Either Screen capture or Screen Capture HX?

I have TPLINK TL-SG108E 1Gigabyte Swtich, My lan cable was Cat 6A, All Connected in Same network,

But still i have this Problm Kindly help me about this,

one more Doubt is there any ip setting for PC.

Have you tried vMix Desktop Capture instead of the NDI tools already?

If a few NDI sources work and the more you add the more laggy it gets it's definitely a sign of a network overload. I made a clip to demonstrate how quickly even with a few source the network can be saturated.

Hope that helps.
