He he. I like how they downplay this method to promote their own UE3 engine :)

They already do to a certain extent... straight from the article,

"Tim Sweeney, architect of the Unreal engine, highlights further visual challenges of using deferred rendering. “It’s faster for large numbers of lights and shadows, but the drawbacks are increased video memory usage, and artistic limitations as you force all objects to be rendered with the same material model,” he says “Unreal Engine 3 has an extremely flexible and artist-extensible material system, so we didn’t want to constrain this unnecessarily.”

Another issue is anti-aliasing. “Anti-aliasing is a key to the rendering quality of Gears of War,” Sweeney explains. “If you look closely, you’ll see that all static and dynamic lighting is anti-aliased with multisample anti-aliasing, so moving to a pure deferred rendering approach would be a step backward.”

Significantly though, UE3 does use some deferred elements, re-using z- and colour-buffers and techniques that would be otherwise impractical, such as velocity-buffered motion blur. And Sweeney is happy to concede that future hardware architectures might encourage the further use of deferred rendering. “I expect we’ll see developers inventing ever-cooler deferred techniques,” he says. “But the constraints assure that it won’t become the predominant rendering scheme, at least within this console generation.”"

I couldn't believe what I was reading.

When asked about Deferred rendering he starts crapping on about his own engine that debuted 10 years ago. You sound like a fanboy Sweeny.

And for the record, I thought Gears graphics, looked static, sterile and non-interactive.
