According to scientists who did scientific things using science, Killzone 3 possesses less input lag than its predecessor. This sort of lag was a major issues for some gamers in Killzone 2, so they'll be pleased to know that their bullets will shoot slightly faster now.
The lag was put through its paces by the chaps at Digital Foundry, who used a special controller to gauge the time it took between pressing R1 and firing a weapon. The time was 116ms, which is 33ms shorter than Killzone 2. That probably doesn't make a difference to normal people, but the kind of freaks who lost their shit over the last game's input speeds will likely cream their jeans.
According to the testers, the "weight and heft" of Killzone 2 has been sacrificed for an "overall increase in terms of the quality of the gameplay experience." Part of my enjoyment specifically came from that feeling of weight, but heaven forfend we try to make any other type of FPS that doesn't feel exactly like Halo, right?
I can't wait for all games to become an identical mass of grey sludge.
