What is causing this FPS drop in Fallen Order?

Here is a screenshot of the new Star Wars game with overlay of my cpu, gpu and ram usage. As you can see nothing is close to maxed out, the game runs at around 80 fps on average for me, but in this section it drops to 50 and I'm curious what is causing it. Thanks in advance.
