Even this Pachter got wrong, because I sincerely did not expect any large generational leaps. I find the UE4 demo wholly underwhelming, and that was made by a company that can spare the expense because it needs nice visuals to sell the engine. Dev costs have been spiraling out of control and there's really not that much to improve.
Imagine my surprise when I was pretty much blown away by what was on show here.
I mean, I know it means almost nothing. The DD demo was a closed off space, probably without any AI and stuff, and the Killzone demo was once again a narrow corridor with invisible walls and all the scenery stuff in a skybox. It's all smoke and mirrors and not that computationally heavy as it looks. I wish they'd use the extra processing power to not resort to closed off spaces and smoke an mirrors, but nope. Doesn't matter though, because it did look like a generational leap.
