Wow. When he popped out of full screen and revealed that he was in his editor - mind blown.

I was more impressed by the live recompilation. It didn't interrupt his gameplay at all.

I've been looking for a source on what hardware this demo ran on, where did you figure that out?

It's mentioned in the parent article:

> You're going to need the latest hardware to get access to all that graphical power, though. The demo we saw was running on a top-of-the-line NVIDIA GeForce GTX 680 graphics card, and we were told explicitly that the engine was currently being targeted for the next generation of console hardware rather than the Xbox 360 and PS3

I wonder how well this'll run on the GTX 570 (or two of 'em). Wish they'd release a demo for people to play with.
