I've reported this before, but it's been a few releases now and I think it's time to refresh this topic.

When you load a project with a reflective object in it, and let iClone sit idle in the foreground, it puts a big load on the GPU for no reason.

If you make a different application active (but still leave iClone visible, non-minimized), the GPU load will drop back down to zero.

It makes me wonder how much this "phantom load" could be slowing down rendering, both during real time preview and during final export rendering.

To duplicate:
  • Use a tool such as GPU-Z to monitor GPU load
  • Open the DEFAULT PROJECT in iClone (see image below).
  • Observe the GPU load.
  • Anytime iClone is the foreground application the GPU load is very high.
    • 72% when stopped
    • 90% when I press Play
    • 72% again when I press Stop
  • Anytime another application is active, only then does the GPU load drop way down.

This makes no logical sense to me, and points to some fundamental problem that needs to be fixed.

CPU = Intel 3770K (with onboard graphics)
GPU = AMD Radeon 6850

In this picture, I loaded the default project, but NEVER PRESSED "PLAY."  Look that the GPU load.  You can see where I switched between having iClone or other applications (like GPU-Z or this forum) in the foreground.
