Games consoles have dominated the games market for several years now, with the side effect being the PC usually just gets a console port. And with the Xbox 360 and PS3 now several years old, their games don’t exactly stress the hardware inside a modern PC.With the Xbox 720 and PS4 both shifting to an x86 architecture, that’s sure to change in the next couple of years. But before then we have a game being released that will truly push the limits of your PC if you have the hardware to run it optimally.Metro: Last Light is a first-person shooter that has been developed by 4A Games and is being published by Deep Silver. It’s set for release on May 14 and is the sequel to Metro 2033. With the release date so close, Deep Silver has released details of what kind of PC hardware you’ll need to run it, specifying minimum, recommended, and optimum specs.To play the game you only need a 2.2GHz dual core processor, 2GB RAM, Windows XP, and either a GeForce GTS 250 or Radeon 4000 DirectX 9 card. That’s a minimum though, and Deep Silver suggest you have at least Windows Vista, a 2.6GHz quad core chip, 4GB RAM, and a DirectX 11 graphics card like the GeForce GTX 580/660 Ti or Radeon HD 7870.It’s the optimum settings that really caught my attention, though. Anyone who has played Metro 2033 knows how gorgeous it can look with a decent rig. I expect that to be the same case with Last Light, and 4A Games will have attempted to use every ounce of performance you can add to a system. That means, if you have one of those $1,000 GeForce GTX Titan graphics, Metro: Last Light will take full advantage of it, as the gameplay trailer below should hint at.In fact, the optimum settings for the game actually read like the ultimate gaming rig at the moment. You’ll need a 3.4GHz Core i7 processor, 8GB RAM, Windows 7 or 8, and a 6GB GeForce GTX Titan. That’s not a cheap system to build, but will future-proof your gaming for 2 or 3 years at least.
