I don't have time for everyone's videos but I can say that xLights is running Normal mode and not Enhanced mode. I can guarantee you that if you have all the channels hooked up and are using 512K baud that you have lag.
yes absolutely im sure in normal mode it will lag, in enhanced for LOR I ran all 8 controllers and the show looked great!
I have 8 arches, 6 100 pixel spiral trees with stars, a 20 foot 16 string mega tree, 6 windows wrapped in leds, blowup with leds in it and a few small things like Tune To signs and such that all run off 1 enhanced USB adapter for LOR. I added a second network for a pixel net sign of about 400 pixels (if I remember correctly) to be safe and have it on its own
unfortunately LOR does get ya in on cheaper hardware which worked great but now I know I have to part with it to do P10 panels so I guess im going on a selling/buying spree, lol
