Steam Pretty Bad Hitching/stuttering On Cardiff City With Tsw

I'm having an issue with pretty servere hitching/stuttering every minute or so on Cardiff City ever since TSW 7. It looks and feels like shader compilation or load stutters, but it's not the shaders, as I've driven the route several times already. The problem seems to occur at predictable locations and persists even when I lower my view distance and foliage quality settings. I'm guessing it might have something to do with the dense network nature of the route and tile loading, but haven't had any luck yet with playing around with my settings. I haven't run into similar problems on other routes yet, only Cardiff. Has anyone else had similar issues or even found a workaround?

My specs are as follows:

Operating System: Windows 11
CPU Brand: 12th Gen Intel(R) Core(TM) i3-12100
RAM: 32 GB
Video Card: NVIDIA GeForce GTX 1080 Ti
Primary VRAM: 11 GB
