I wouldn't be surprised if this was partly the company jumping a bit too much on the Nvidia hype-train for Gameworks. So easy to use. Plug and play. We build the effects and modules for you, so you don't have to worry your pretty little heads about it.
Add to that it's UE3 which is heavily Nvidia sponsored with Gameworks, and I'll bet someone in upper management figured they could save a few bucks by just using Nvidia provided bits and bobs as is and it would all just magically work. And I'm sure Nvidia was more than happy to tell them, that they'd help make sure everything worked perfectly.
Only things didn't...and stuff happened.
Anyway, since Rocksteady Studios is a developer I will never ever buy anything from since that whole debacle with Batman: AA, I'm at least not in any danger of having paid them for this steaming pile of a port. Hell and if someone tried to gift it to me on Steam (how I got Batman: AA), I'll probably just give it right back.
