I have been doing some rendering tests recently using the Advanced Camera to render spherical images. I noticed it only uses 25 - 50% of the available CPU processing power. Is this because it is not properly coded for modern multi-threaded CPUs?

What version of LW are you using? Here's what I'm getting with the Advanced Camera in LW 2015.1 (rendered on 6 cores, 12 threads)

Cylindrical FoV 120 degrees:
70%-100% CPU utilization // Radiosity
90%-100% CPU utilization // Main raytracing/antialiasing (blue bar)

Spherical FoV 360 degrees:
50%-100% CPU utilization // Radiosity
65%-95% CPU utilization // Main raytracing/antialiasing (blue bar)

I think I was using 11.6.3 when I tested it I will have to try 2015 when I upgrade soon to see if there is any difference. It looks like there might be according to the numbers you posted.
