If GPU then the plug-in will transfer the frame to GPU, do the compute and then read back from the GPU to system ram. To pass to an OpenFX plug-in it has to read back from GPU to system ram, possibly convert component data bit depth, then pass this frame to the plug-in. Resolve keeps the frame internal in GPU memory. With GPU dataflow pipelining is everything. With effects this involves the GPU as well. It is not a custom fit to the application internal dataflow.
