FPS Drops with Pawn Movement

I’m getting framerate drops when moving a spacecraft pawn.

Does anyone know what could cause lower framerates only when a pawn is moving?

UPDATE:
I figured out what was causing the framerate drop.
The collision for the fuselage is too complex.
I will need to swap meshes when in flight to use the one with less complex collision.

I think movement in general is more demanding than not moving.
I wouldn’t necessarily be looking at the movement but general optimization. It’s already very low when not moving.
Having 2 cameras is heavy, what resolution the 2nd camera is, what resolution the landscape is, shadow maps, Lumen…

I had already tried general optimizations yesterday.
