Adding my take on this too.
Having laptop with GTX1060 and i7-7700HQ. In all areas with frame drops GPU is not utilized enough (running at around 30-50%), suggesting that CPU bottleneck appears.

Fires are necrofires are especially bad. Only option that looks to be helping is turning off shadows completely. Blackpits oil rig battle was especially bad.
