We suggest watching these in HD to see the highest level of detail.

Watch Dogs: PC
Notice how the Xbox One's driving video may not be quite as high on detail levels, but is smoother overall? On the PC, those occasional micro-pauses are what happens if you play the game at detail levels approaching the maximum your GPU can handle thanks to limited VRAM.
If you keep running the sequence or adjust the detail levels even slightly upward, the game pushes back hard. Here's how performance degrades after several additional runs:
Watch Dogs: PC -- Repeated driving sequences
Both of the PC driving sequences were recorded using High Textures, High Details on a 2GB GTX 770. The only difference is that the first sequence was recorded immediately and the second video is recorded after several more race attempts. If you want to avoid these types of stutters and pauses altogether, you need to use Medium Textures or Medium Details on a 2GB card or less.
These sequences, however, are an indirect comparison -- for a more apples-to-apples look at a mission, Marco and I captured the first criminal takedown sequences in the game. Aidan leaves his fleabag motel for the first time, jogs down to a local park, picks up a potential crime in progress, and heads out to stop it.
Gameplay: Xbox One
Marco and I played through this mission at different times of day, which accounts for the difference in ambient lighting. Outside of that, it's nearly impossible to tell which version of the game is which. The Xbox One is still using its peculiar 792p resolution and you can see the difference on jagged lines -- the PC's 1080p + FXAA combination is still significantly better -- but overall, the Xbox One version of the game is surprisingly good. If you expected the difference between the two to be night-and-day, it simply isn't.
