I have a modest HP Pavilion laptop G32. Usually MC runs around 1% or less CPU time. Just noticed that MC20 - possibly since the last release - is running at 10-11% CPU. Not doing any processing/DSP or anything just playing back FLACs. Have now stopped playing for a few minutes while I type this, and it is still running at 11%. Went through the same about half-an-hour ago, and re-started MC so there's some element of repeatability. Annoys me, because it makes the fan come on!
