after now being able to play some old games on my amlogic box I figured, that Kodi, which is running the c64 vice emulator is saturating one of 4 cores in my amlogix S905w device. One can hear it during playback of games music and one can also see short glitches in display. Eventually ever 5-10 seconds for ~ 100 – 200 ms.
It can also be observed e.g. by running the deus ex machine demo available from here .
After some experiments I figured, that reducing the screen resolution of the display can reduce the cpu utilization to like 15 % overall … however the glitches an lags are still observable.
I can observe a similar behavior on my x86 Atom D525 box with 2x1.8 GHz …. However much less occurrences of lags … eventually every minute once …
Actually I have run the CPU benchmark addon on both systems and I can see better benchmark on the amlogic system … however I know that a python benchmark is not really representable
Does anyone experience the same issue ? Or has an Idea how to solve that ?
Next thing I will try is if I see the same on RPi3 …
Any comments appreciated ….
