Black Ops 2 Game Director: What Exactly is There to Be Upset About with the (CoD) Engine?

If there's one Call of Duty haters like to continuously bash, it's the franchise's game engine and how it makes everything look similar in every game. 

This concern has been compounded even more last year with DICE's release of Battlefield 3 and its vaunted new game engine, Frostbite 2. 

In an interview with OXM, Black Ops 2 game director David Vonderhaar remarks that the 60 frames-per-second (fps) has been one of the series' hallmarks and that's what fans "love in the first place."

Anybody who comes at the engine needs to remember it's the 60 frames they love in the first place…And we can make it beautiful – that's through years and years of working with the engine, improving upon it and improving the pipeline and improving our approach, our lighting rendering.

Vonderhaar even goes a step further and states that he "never understood" the complaints the Call of Duty engine receives. 

To me, it's like I never really understood…It runs at 60 and it's gorgeous. What exactly is there to be upset about with the engine?

Do you agree with Vonderhaar's statements or do the developers really need to revamp the base engine of the Call of Duty franchise? If they did, wouldn't people complain about it being "too new?"
