We played through the tech demos from E3, and they remained fun.

For what amounts to a $2 tech demo (or commercial if you want to look at it another way), Rage is a great showing.

In essence, the whole thing is a tech demo.

A second tech demo was released on February 26, 2008 showing the realistic use of fire with various objects in the game.

Before the game's release, a tech demo was released that included four single player missions, with one being a training mission.

It would be hard to believe if the tech demo wasn't already in our hands, in fact.

This is a great tech demo for the engine, and that's all.

Penumbra itself was originally a tech demo created in 2006 to show off the technology.

A video of the tech demo was released in early 2005, weeks before closing.

We also watched a tech demo showing some high definition graphics, but that's not the point.
