SharpDX - high GPU usage

Jun 11, 2014 at 11:41 AM

why is the GPU usage so high, when I start the ImageViewDemo or other examples with SharpDX.
I use the processexplorer detect this.
(IDLE > 20%, Rotating > 50 %)

A "normal" DirectX-Application (no SharpDx) uses on my System < 5% GPU.
Is this usual for applications using SharpDX?
