Presume this is a Resolve Pro (paid version not the free) and you have both Titan X cards enabled for CUDA.
What are your settings for playback scaling presuming you are scaling the r3d to a timeline with different pixel aspect to the camera original. I have had no issue getting 25fps with a single Titan X playing 8:1 r3d scaling to HD from a Dragon.
Should add my settings for scaling are for best playback and the final renders are to force best debayer etc
