Yeah, you also aren't going to handle metro last light. Period. :P
If it's anything like the original Metro, it's so poorly optimized that three years after it's released, the BEST brand new hardware can't run it maxxed out with a minimum 60 fps.
just like the original crysis. Short linear first person shooter game that runs like shit no matter what. Used for quite some time as a "benchmark game" but once the fancy new graphics and physics lost their sheen, and it still ran like shit on monster rigs, it became obvious that the game didn't have huge requirements due to "next-gen" features, but more so due to a lack of good optimization of the game engine for existing hardware.
