Dacast recently published an article, "How To Stop Computer From Overheating While Live Streaming". Pretty interesting read.
What they suggest is to counter overheating your computer while streaming is to use a hardware encoders rather than rely on software. They do say however that software encoders are more robust in what you can acheive over a software encoder.
Thing is, I have not had any overheating problems using vMix when streaming. Or anything else. All of the bencmarks in my desktop and laptop stay are well within vMix's suggested limits. Those benchmarks suggested by vMix are, render time and CPU load. vMix suggests a render time of 20ms or less and CPU load of 70% or less.
In DaCast's orginial article post they named a couple of popular software encoders in this article. Those software encoders have since been edited out of their post.
As I remember, vMix was not named in the orginial post.
DaCast also suggests re-greasing some things in your computer. Next time I talk to my computer mechanic I'll ask him about that but it's something I'd ever try on my own (LOL).
Here's the link to the DaCast article if you'd like to read it http://www.dacast.com/bl...g-while-live-streaming/.
