Not utilizing Nvidia card

[noobtoob4lyfe]

Apologies if this is a noob question, but when I run a movie through BF it makes my cpu usage go to about 90% and my videocard usage remains flat. I ran .\butterflow -d and got the following.
Any suggestions? Do I need to add something to the command to activate hardware acceleration?
OpenCL devices:
Platform : NVIDIA CUDA
Platform Vendor : NVIDIA Corporation
Platform Version : OpenCL 1.2 CUDA 10.0.132

• Device 0 : GeForce GTX 1080 Ti
  Vendor Id : 0x10de
  Version : OpenCL 1.2
  Version : 416.34
  Work Sizes : 1024, 1024x1024x64
  Compatible : Yes

Try using the -device option: butterflow -device 0 <other args>

Thanks very much for the suggestion.
I am using that option and the graphics card usage is about the same (somewhere between 3 and 5%).
CPU usage is up to 70 -90% though. Is this normal?

It might be selecting the wrong device. Run with -vv to confirm your GPU is being selected.

Thanks again. Here's what it printed out.

Maybe ffmpeg needs to have HW acceleration enabled somehow?

I'm not able to get it to leverage my Nvidia GPU either. It detects it fine with -d and the verbose messages says it auto selects the GPU and hardware acceleration is on, but my GPU usage never goes above a few percent.

Here is the verbose output from running `butterflow -r 2x -v video.mp4':

Try using the -device option: butterflow -device 0 <other args>

Thanks you. That's work!

Has anyone apart from NgocSon159 solved this?
