I use to use my rpi3 which had retropie install on it also as a plex server and had torrent software on it, I used it like that for around 8 months and everything was fine but the only problem I had is I use to take the pi to friends houses alot at weekends then the kids use to moan that they couldn’t watch anything on plex whilst I was out lol.
But it seems retropie uses less resources when idle than magic mirror does.
For example if I enter “top” on my magic mirror electron is running twice and cpu usage is around 25-30%.
Retropie on the other hand idles around 1-3% only even going up a couple of percent whilst streaming to my smart tv.
I think I’ll just have to pull out one of my spare memory cards and see what happens I think.
For sure I’ll post back my results here just for everyone else’s information:)
