<pre>Software rendering is surely consuming CPU for it's using CPU to do the job of
rendering, which contains lots of calculation. It's only a fallback if GPU
can't be used somehow. Even a simple opengl application can eat up ~40% of CPU
on my machine if I use software rendering.
In my knowledge, software rendering under DRM backend is not supported. You are
using your gpu even if you specify LIBGL_ALWAYS_SOFTWARE, you can check your
log for that.</pre>
