[PROBLEM] XBMC idle CPU at 80%

[JayBlanc]

Maybe patch xbmc/Application.cpp to change the "unsigned int singleFrameTime = 10; // default limit 100 fps" line to "unsigned int singleFrameTime = 3; // default limit 30 fps"

I don't think this affects video playback, just the gui. Even if it did, there's not much that the RPi can play back above 30fps in software.

High CPU use when scrolling text *can't* be fixed in XBMC unless they ditch their current GUI render system, because it constantly polls for changes and then renders them as fast as it can up to that 100fps limit. Yes, there's absolutely no reason to render scrolling text at 100fps, but it happens because they also wanted to use the XBMC gui to render high frame rate visualisations.
