Thanks for the great list of resources for debugging gpu performance! Android GPU Inspector and http://shader-playground.timjones.io/ http://shader-playground.timjones.io/ all look pretty cool. Do you have any other debugging tips or tooling recommendations for a complete graphics noob? I have only done one webgl project before but that experience was pretty painful. When writing my first glsl shader I basically committed every performance sin possible. Like in your case, the slowness is hard to notice on a beefy desktop, it was only on mobile devices when it becomes apparent. My debugging process was then to comment out lines, rerun, and squint at the fps. There must be a better workflow than this! (iirc, my issue was that I was using "discard" in my fragment shader which is apparently especially bad on powervr architectures https://stackoverflow.com/questions/8509051/is-discard-bad-for-program-performance-in-opengl https://stackoverflow.com/questions/8509051/is-discard-bad-f...)
