Hello, I am trying to get Mandelbulber to recognize the available OpenCL on my GTX 1080, but it does not seem to be able to find the platform. Does anyone have any tips to troubleshoot this by chance? Any direction would be much appreciated.

I'm open to the fact that this might just be me not being able to find the UI element to enable it, but from the troubleshooting so far it looks like the nvidia platform is not recognized.

Mandelbulber Version: 2.19
OS: Windows 10 LTSB (up to date)

I'm new-ish to openCL, but I did get the following output running  --help-opencl. I've also included a screen cap of GPU Caps Viewer showing an available OpenCL platform
There are no platforms listed when running

C:\Program Files\Mandelbulber2>mandelbulber2.exe --help-opencl
Mandelbulber 2.19
Log file name: C:\Users\Kevin Stoddard\mandelbulber_log.txt
Detected 8 CPUs
Program data files directory C:\Program Files\Mandelbulber2\
Default data hidden directory: C:\Users\Kevin Stoddard\mandelbulber\
Default data public directory: C:\Users\Kevin Stoddard\mandelbulber\
Mandelbulber can utilize OpenCL to accelerate rendering.
When Mandelbulber is already configured to use OpenCL, it will also run OpenCL from commandline by default.
The configuration can also be done directly from this commandline by setting the optional settings directly.
These can be given by the default --override option, available opencl specific options are:
 * opencl_enabled      - boolean to enable OpenCL
 * opencl_platform     - platform index to use, see available platforms below
 * opencl_device_type  - Possible device types of the platform to use
  `- possible values: [gpu, default, all, cpu, accelerator]
 * opencl_device_list  - right now only one device at a time is supported.
 Specify the device hash of the device to use, see available devices below
 * opencl_mode         - Mode of the render engine, 'fast' has no effects, 'limited' has basic effects, 'full' contains all shaders.
  `- possible values: [none, fast, limited, full]
 * opencl_precision    - Floating point precision of Render (single is faster, but less accurate)
  `- possible values: [single, double]
 * opencl_memory_limit - Memory limit in MB

Available platforms are:

Available devices for the selected platform (0) are:

What is visible in Preferences window (open from File menu) on tab OpenCL? Is the list of platforms empty?
It should be visible something like on screenshot.

Ah, it was that simple. My GPU showed up in there and it's rendering with opencl now. Thanks for the direction.
