We're going to be taking a closer look at Bruce Wayne's secret identity on PC soon, but until we do there's a rather shiny "showcase" trailer showing off how implementation of physics engine tech looks on nVidia-powered PCs. Stuff swirls and swishes and dudes get kicked. It's quite impressive. It's still the same gloomy, doomy Arkham Asylum, but there's quite a lot more detail. And, my, it is good lookin'.
For those that missed it: there's a demo out.
