what do you game on now?
I only ask because I almost didn't buy my plasma because I heard it had really bad lag(and it does) but did not realize that I was already used to playing on a plasma with almost as bad of lag. ppl were claiming the lag on game mode was still worse than most displays, but it was actually very close to what I was used to.
I think you're very correct to worry about it, it's just good to keep it in perspective. would be a shame to cross a great projector off your list because it has the same lag as what you're currently using(unless you're unhappy with your current display's lag)
the jvc I just bought is better than the plasma(Samsung f8500) for lag. but far as I can tell there's no game mode or anything to help with the jvc. still, I can't say i've noticed anything. FPS's and NHL13 feel normal to me.
