Project Natal's Lag Timed at 1/10 of a Second

Ever since our hands-on, we've been shamelessly excited about Project Natal...except for one key piece: The slight but undeniable lag. And now, MTV has actually put the difference between your movement and onscreen response to a stopwatch.

Over the course of several demos, MTV found that the lag ranged from .08 seconds to .12 seconds, and .10 proved to be a pretty consistent average. (You can time .10 seconds here.)

During our demo, I likened the delay in a driving game to steering an old Cadillac. Indeed, as an input device alone, such a delay will mean certain gameplay situations just aren't possible (Natal might not make the best jet simulator).

However, I still see the delay as a non-issue for the aspect of Natal that's still gone without mention by most publications—that of head tracking. You'll see what I mean in this demo by Johnny Chung Lee who, it just so happens, works on the Natal team now. The same can be said for vocal commands, facial recognition, and heck, even just spotting your exact position in a room. [MTV via Kotaku]

So does Wii.

Well given that a standard wireless controller is 0.06 second, they aren't too far off that mark. Also from what people here and other places have said, KZ2 has 0.16 seconds of lag so ..

That said, even 0.06 seconds it too much lag for me for certain kinds of games, I can't stand playing FPS and shooters with a wireless controller.

Your TV has ~0.1 second lag, too. Nobody notices it except when playing Guitar Hero games and the like.

0.1 sec. outrageous!!!

but is it a significative problem for the gameplay ?

I doubt.

why its always tested and a empty white room fluorecent lighting

it's not 1-1 still, and both wii motion plus and "arc" are.

A 100 ms delay is pretty standard, but it also looks like this person did not do a very good analysis, at least in describing their methodology. Digital Foundry does a much better job.

It's hard to know what this really means. .1 seconds = 100 milliseconds. When you do stuff like music, anything more than 14 ms of lag (difference between hitting a key and hearing a note) becomes completely unusable. I've got no clue how that translates to games though. Especially reading ramses101's post about standarad wireless controllers have 60ms of lag.

If the lag is similar to a Wii-mote, there shouldn't be any issue unless a game has you batting away bullets in real time.

Latency was always one of my concerns for Natal. 0.1 seconds is noticeable but certainly not game breaking. It really comes down to the type of game you're playing. If it requires extremely precise twitch controls like most racers than it becomes an issue. Obviously nobody is going to be playing Rock Band or Guitar Hero with this though. For most games that aren't super hectic it shouldn't be an issue.
