Command Line Rendering with EEVEE is slow
Open, NormalPublic


Win 7 Pro 64Bit
GTX 1070
Driver: 417.22

Blender Version

If I render with EEVEE via Command Line, the GPU Load is around 40-50% (4min 33sec).
Rendered the same scene in a normal way via Gui, the GPU Load is around 90-98% (3min 20sec).

If I render the same scene with Cycles via Command Line, the GPU Load is around 90-98%

blender -b PathToBlend -a

I've tried several scenes with the same result all the time.

I can not reproduce this in Linux. I get the reverse (and that is to be expected if it works correctly).

inside blender: 02.43
from command line: 01.08

Could be a driver issue or something we are doing bad on our end. Difficult to say. "Minimized" applications may have lower priority to the GPU.

Cycles is a different beast and does not use OpenGL for rendering so no surprize about that.

Thank you so much for your trouble.

I just searched unsuccessfully for a program to increase the GPU priority.

If any of you are using Windows and do not have this slowdown, please post your Nvidia driver version.

I have now tested half a dozen drivers (current version 399.24).
No change.
