You know that amazing Unreal Engine 4 "Elemental" demo that's been wowing us ever since GDC 2012? You can now download it and run it on your own PC. There are very few games that currently use UE4 (they're all in the pipeline for release later in 2014 and 2015), so it's a good opportunity to see how your gaming PC's hardware deals with a next-gen engine. And yes, there is a built-in FPS counter -- and I expect you all to share your rig's FPS in the comments!
