I have a Threadripper 3960X system with NVIDIA RTX 3090, 64G of RAM and M.2 HD using studio version of NVIDIA drivers. I use Davinci Resolve and BCC OFX. When I use the BCC BeautyStudio filter, my playback and render times become 0.5-1.5 frames per second. I have set the GPU usage in Davinci Resolve to CUDA and I have the check box for use OpenCL on the BCC plugin. The resolution of the source is 4k Canon Raw, 5K Blackmagic Raw.
Timeline perfomance with nodes that have BCC cause the FPS to grind to a hault!
