OpenFX args.isEnabledCudaRender returns false

I'm compiling the OpenFX Gain project but I can't get any GPU rendering working in Fusion.
When debugging isEnabledOpenCLRender, isEnabledCudaRender and isEnabledMetalRender are all returning false from setGPURenderArgs in ofxsProcessing.h

I have made sure GPU is enabled in Fusion. I have also tried manually set the device to GPU and the API to Cuda and OpenCL in Fusion but it still returns false.

When I open the plugin in Resove, isEnabledCudaRender returns true but isEnabledOpenCLRender still returns false.

Is this a bug for Fusion or am I missing something to make it work?
Also, should OpenCL work in latest Resolve/Fusion at all? Wondering as it returned false for both softwares.

Bonus: I would LOVE to get an OpenGL template project in a later release also.

Hi Jacob,

have you found out if there is any way to use OpenGL in an OFX dll with DaVinci software?
I'm still searching for an option.
Our software is native in OpenGL and can be used as a library in OFX plugin (e.g. Gain).

Just wondering, is anyone aware if anything has changed over the past 3 years?

Thanks in advance.
