On May 22, 2014, a Redux version of Metro Last Light was announced. It was released on August 26, 2014 in North America and August 29, 2014 in Europe for the PC, PlayStation 4 and Xbox One. Redux adds all the DLC and graphical improvements. A compilation package, titled Metro Redux, was released at the same time which includes Last Light and 2033. (Wikipedia). We test with following settings: Quality-Very High, SSAA-off, Texture Filtering-16x, Motion Blur-Normal, Tessellation-Normal, Advanced Physx-On.
1080p performance is good. Unless you are happy lowering image quality, both GTX760 and R9 285 will not be able to hold smooth 25+ frame rates powering this engine at 1600p. No point trying 4k testing.
