[PC] FH4 Extreme Stuttering When Playing On Low Settings, But High In Benchmark Is Just Fine

[ShiftySneeze21]

When I am playing free-roam or anything, I get extreme stuttering and lag, GPU usage goes up, on low settings.

When I run the benchmark on high settings, it does it just fine.

SPECS:
GTX 1060 3GB
i7-7700K
8GB

I am not overclocked.
