Strangely, they've started lagging, but only in vMix. We tested it in OBS and it ran smoothly. Has anyone else experienced this? If so, please share how you solved it. Updated license,

Updated license, Check your Network connections, especially at the PC. You may have a 100mbps connection instead of a 1000mbps (Gigabit). Gigabit is recommended minimum speed.

Absolutely, with fluctuating power all manners of equipment could be crashing and restarting andi for network equipment that could cause it to lag.
