Shadertoy Visualizations Raspi 2

1st Official Post

    Hi All...

    I recently purchased a Raspberry Pi 2. I had installed kodi on my PC, and found some visualizers that I liked. Thus, I decided to put
    LibreElec on the Pi. However, the music visualizations slowed down the whole UI, which led me to overclocking.

    What can I do to fix this?

    Thanks in Advance,
    ChownClown

    P.S: I'm running LibreElec 7.0.2

    Pi devices are amazing for what they are, but they are also a $30 hobby board with limited CPU. Some visualisations are OpenGL and will be handled nicely through GPU decoding. Others require CPU and will be challenging on low-spec hardware. Most Kodi devs use mid-range x86 hardware with a lot more CPU power for development so it's not too surprising that some Kodi eye-candy puts a Pi board beyond its limits - it was never the design target. The easy option for a small speed bump is moving from RPi2 to RPi3 but that may not be enough and the real step-up requries to you move beyond Pi to something more capable. You don't always need to look at the latest/greatest (most expensive) kit; it depends on your media playback needs. I'm still using an older Atom/nVidia box as my main player device. It's nearing 5-years old and is up for replacement as it can't handle newer HEVC/1080p/4k content that I need to test with now, but it still has 3.5x the CPU grunt of an RPi3 and plays H.264 content perfectly.

    Which specific visualisations are you trying to use?
