By the end of this year we’re definitely going to have one, and probably two new next-gen consoles to play with. And the spec and feature bump each will include, such as Sony improving DirectX 11 for the PS4, means game engines need to be updated to take advantage of the extra power on offer.One of those engines is the very popular Unreal Engine. The current generation of games use Unreal Engine 3, but next-gen hardware will use Unreal Engine 4. We got a glimpse of what UE4 could do back in 2011 when Epic released an demo video. But that was two years ago, and we’ve yet to see what it’s truly capable of in its final form.The video above has been leaked today, but should see an official release before the day is over. It’s called Infiltrator and is one of the demos Epic is showing off during GDC.It’s certainly impressive and shows off what Unreal Engine 4 can achieve with visuals. Whether this is the quality of gameplay visuals or not has yet to be confirmed, but in-game cutscenes created using the engine rather than pre-rendered scenes is more likely.There’s no doubt we will see a visual quality jump with the new hardware. This demo bodes well for how much of a jump we can expect to make, but as usual, it’s going to take a few generations of game before we see what the PS4 and Xbox 720 can really do. Just look at the first PS3 and Xbox 360 games and compare them to The Last of Us and Halo 4 to see what understanding the hardware can do to improve things.
