Hi guys, I'd like to find out how much CPU usage is consumed when playing a 720p mkv file on my VMC player. I opened Activity Monitor and it's showing a lot of things, 1. There's CPU usage right next to VLC program which is reading between 30 to 45. 2. There's also CPU usage meter in the lower left corner in 4 different types; % User, % System, % Nice, % Idle ---- Now, my question is, what is the difference between #1 and #2? And can you explain to me what % User, % System, % Nice, % Idle are in simple terms?
