L515 Framerate

After alignment to depth, the framerate drops from 30fps to ~20fps even though both depth and RGB streams are set at 30fps.  How can I get the framerate back to 30fps or is a drop in framerate inherent to aligning to depth?

cfg.enable_stream(RS2_STREAM_DEPTH, 1024, 768, RS2_FORMAT_Z16, 30);
cfg.enable_stream(RS2_STREAM_COLOR, 1920, 1080, RS2_FORMAT_RGB8, 30);
rs2::align align_to_depth(RS2_STREAM_DEPTH);

 while (RunSet->SystemStarted)
    {
        // Block program until frames arrive
        rs2::frameset frames = p.wait_for_frames();
        frames = align_to_depth.process(frames);

    Turns out the auto exposure settings were causing a reduction in framerate.  I have no idea why they would be different but after setting them to a constant the camera returned to 30FPS.
