Vulkan Mouse Lag With Serious Sam

At the start of Sand Canyon, if you look behind you at the beetle door with no fire torches, mouse movement will lag heavily.

At the start of Tomb of Ramses III, if you move to the left or right in between the pillars, and look left and right, mouse mouse movement will lag severely. It still occurs even when transgressing through the map. I remember this happening a while ago, and thought it would iron itself out as Vulkan matured, but its still occurring.

Im using NVIDIA proprietary drivers 418.43, Vulkan version 1.1.102, and Xorg server 1.20.4 on a fully up to date Arch Linux. My full system specs are in my Steam profile.
