If you played inFAMOUS: Second Son and inFAMOUS: First Light you very possibly thought that Fetch is much faster than Delsin, truth is that she really isn't that much quicker, but the folks at Sucker Punch used their technical wizardry to make you think she is, as explained by Visual Effects Artist Matt Vainio and Game Designer Darren Bridges during a panel at PAX Prime.

You shouldn't feel bad if you've been tricked, as Bridges explained that after seeing Fetch's neon dash in action the Director of Development went over to his desk mentioning that he liked the effect, but Fetch was moving too fast and overtaking the streaming speed limit of the PS4. Yet, that wasn't the case.

All the visual tricks used to make her feel faster actually deceived the Director in thinking that she was too fast and she would have caused problems with the engine, but her actual speed was actually within the limits.

To demonstrate how it works,  he shown a "race" between her and Delsin, and the difference is very visible.

We also get a lovely explanation on the work done on Fetch's melee combat and on her Singularity move in order to make them appear more impactful.
