We used a 2015 i5 at DebConf18 and we had a lot of trouble. We had to
reduce the preview quality a lot since we were loosing frame and were
experiencing audio desync because of a high CPU usage.
I think the main difference between our setups is we have a 2nd camera
and thus 3 sources.
From our tests the linux kernel patches for Specter (KPTI) also has a
large impact.

But you don't have an audience camera that is 50+ meters away from the
mixing PC :P
