Display MoreI'm assuming "Radio" by Tristan Fischer as there are many other"radio" addons.
I've tested on a RPi2 and yes there is a burst of cpu activity at first start, but this settles down once the buffer has filled. Leaving it on the selection screen increases the cpu to > 50%. <Tab> brings this down to 25%.
Are you using a visualization and if so which one?
Shadertoy didn't cause any unwanted increases in usage..
However, my temperature doesn't go above 55 degrees, so there is something else wrong with your machine or setup.
Use "top" to see what is causing the high cpu usage and try disabling spotify/tvheadend and other addons, to see if they reduce the CPU.
Thanks Iridium , yes its Radio by Tristan Fischer.
No visualization.
Spotify works well without the thermometer symbol showing up.
Thanks
