Freetrack interface use in IL-2:CoD

A PS3 cam or a Wimote can be used with FT to have 120fps tracking (from what I have read).

I'm actually thinking of getting one of those PS3 cams, i'm just waiting to see if CoD will support freetrack first.

I had a trackIR4 which died, i tried FT as an alternative with my standard 30 FPS webcam and the trackclipPro that i already had and i did notice it's slower to react than trackIR. I wouldn't mind getting a used PS3 cam with 120FPS if CoD supports alternative head trackers.

With a current mid-range PC the CPU load of FT is negligible. I think it's the 30FPS webcams that cause this slight delay, plus my own has a somewhat narrow field of view which further complicates things: i sometimes need to move around in weird angles to compensate for my crappy profiles and then it loses track of the dots at certain points

What i'd really like in Freetrack is an interface more like the one used by trackIR for setting up the response curves, as i can't seem to get a good profile for FT no matter what i try. As for the rest, it is a very capable alternative and i guess that using a 120FPS camera would get rid of most of the slight delay between actual and in-game motion.

why don't you just get the real thing, instead of a sponge that offers less than optimal performance?

everytime somebody talks about freetrack you come in and say your idiocy...
why don't you go to hell and shut your mouth? you are only a spammer

Or you could stop taking it so personally and just not reply.

FT uses a x4 multiplier for the data captured by a standard 30fps webcam to overcome the lower frame rate. In use I havent really noticed much difference in performance using a 30fps webcam with FT compared to my 120 fps TIR4 kit. A PS3 cam or a Wimote can be used with FT to have 120fps tracking (from what I have read).

That x4 multiplier quantizes between samples taken from the lower framerate of the webcam which enhances accuracy the same as "smoothing" on a mouse or TIR. The unfortunate trade-off for using a quantizing algorithm is input lag response which is unavoidable.

With TIR for example, I keep the smoothing fairly low, around 15% because the benefit of a little more precision is negated by the lag it introduces. It's not as noticeable on newer mice because of the insane sampling rates they work at now don't really require it.

You may not think you notice it but it definitely affects the way you pivot around in-game, even by milliseconds. You can equate it to playing an online FPS shooter game at 50ms vs 200ms, not as a direct comparison but to illustrate that sub-second lag can have a big impact on your effectiveness.

and who are you to tell me that? you know nothing at all of what he told me in other posts, so is just not your business

Actually I do since I read them.

It's just that you have been far more offensive in your responses than WolfRider has, you just don't see that since you're too busy clutching your pearls in indignation.

Not sure if my settings will suit you BlackdogKt but they may help as a starter. These are for 6DOF which I use with a MS VX1000 30fps lifecam. You will see that I have dumbed down the roll, sideways and zoom axis with varying amounts of deadzone to suit each axis for my preferences. I tried this profile with my TrackIR Pro Clip (vertical LEDs) rather than my Hatclip (Horizontal LEds) - it needed a little bit of tweaking on some of the axis.

I will fire up my TrackIR (which is safely tucked away for CoD duty if required..) and concentrate on the issue of FT's response/lag times and wether it affects my game. It may well be that I haven't percieved the problem due to the fact I set my axis curves for a small deadzone , slow initial movement to the side and then rapid acceleration to my 6 (on both systems). If you are correct, and you may well be, I will look into getting a PS3 eyecam as I prefer FT with IL946 + 6DOF.

The lag that people talks about is a webcam limitation that the max framerate is 30 not the software (if you fine tune your curves you'll not notice any), but with a ps3 you can get 125 fps at 320x240 and 75 fps at 640x480

I use FT with a PS3 Eye with no lag. And yes - I tested TiR products. It's the same thing.

Simple as that: use some "webcam" with more than 100FPS and the magic is done, but cheap 30FPS webcams provide good experience too.

Waiting for Oleg's response about FreeTrack suport. Any word?
