I use my Samsung for my PS3, 360 and PC. I set everything up for V-sync when PC gaming because I've only got a 60hz model so there's a lot of screen tearing in games that try to go over 60 frames per second.
With consoles I haven't had any issues with lag whatsoever so maybe I just got lucky and wound up with a good TV for it. It's only 32 inches so that has something to do with it, probably. So I haven't used Game Mode personally. But I can recognize its usages.
