There comes a point in every hardware cycle where the PC, thanks to its ability to be constantly updated, begins to pull ahead. Do things a console shooter can't do. We're now reaching that point.
While Battlefield 3 is probably the most prominent example of this, with the astounding visuals of its PC edition, I'm quietly excited about Bohemia Interactive's ArmA 3 as well, mostly for the reasons you're about to see in the video above.
The action kicks in at the 0:43 mark, but keep watching until the end, where you'll see what's surely the best video game water ever made.
