It's one of the main complaints about S3, and everything is slower than in other games. That the clunky camera are the biggest signs that the transition to 3D was not exactly seamless. Viki takes a little while too; I am always the happiest to get her in S3. Everything else about the game is great.
It's interesting that in S4, everything is lightning fast and super easy and streamlined (with the sole exception of the encounter rate while sailing, ugh), but literally everything else is worse.
