Scrolling timeline out of sync with audio output

[Billy86]

Working in Superior Drummer 3. Follow host is on. Often, but not always, the problem is that the scrolling timeline doesn’t match the sound generated by the hits/MIDI events  in SD3’s Midi grid. When the hit generates the sound (say, the snare) the timeline is visually and noticeably past the midi event that triggered that sound. Makes it really hard to fine tune anything, as it’s trial and (frustratingly) error. The processing load on the engine/CPU is not that heavy, but it seems latency is at play. The buffer size is at the highest possible. 
 

Is there a setting I can adjust to get things  to line up? Plugin delay compensation? Thanks.
