Question Watch Dogs: Legion i9 9900k 100% usage

[xiantianhan]

Having some real problems with this game. Running around inside buildings is fine, but as soon as I go outside (especially driving around), my performance tanks, with fps dips down in the 45 region. My CPU (i9 9900k) jumps to 100% usage frequently, while my GPU (GTX 1080) sits at around 60%. Surely, I shouldn't be experiencing a bottleneck on an i9 9900k?!

Specs:
i9 9900k
16GB DDR4 RAM
Asus Strix gtx 1080 (overclocked)

These are the current settings I'm running (although I have knocked some down to low with no difference)...
Geometry - Very High
Environment - High
Texture Resolution - High
Texture Filtering - Ultra
Shadows - High
Headlight Shadows - Off
Reflections - Very High
DoF - Off
Motion Blur - Off
Bloom - On
Ambient Occlusion - On
AA - TAA
Subsurface Scattering - High
Ray Tracing - Off
DLSS - Off
Extra Details - 0%
Temporal Upscaling - 100%
Sharpening - 0

Are you at 1080P? (It's harder to get 100% GPU usage at lower res)

If your framerates are good (compared to other users with similar hardware playing Watchdog), I'd not worry about assorted ratios of usage...

My framerates are all over the place. I generally get 60fps when inside a building, or 55-60fps when running around outside. As soon as I start driving though, my framerate takes some crazy dives, all the way down to 40ish fps. I just find it puzzling that it's causing 100% load on an i9 9900k on almost every setting combination.
EDIT: Yes, I'm playing in 1080p.
