The next-generation of game consoles is quickly approaching, but there are some who claim that we don't need new hardware. The argument usually focuses on how there's still ways to squeeze more power out of the current generation of consoles, and how games still haven't reached their full potential.
At GDC 2013, Epic Games smashed that argument to bits with its latest real-time demo of Unreal Engine 4. The technology on display just isn't currently possible on existing consoles, and it's exciting to think what developers will do with it once they have the power to do so.
The most exciting part about this tech demo is that it's running on currently available PC hardware. Epic confirmed that the demo was running on a single, unmodified Nvidia GTX 680. So, we know that Unreal games built on the PC will look great, but it will be interesting to see how the engine works with the AMD hardware in the PS4 and next Xbox.[h/t: Polygon]
