I'm using a cheapie Philips SPC300NC/00 webcam and I had it set on default 30fps. Playing ArmA which is very CPU intesive I was getting quite slow response to head movement. After lots of fiddling I tried setting the camera and FreeTrack fps LOWER. Camera set to 5fps FreeTrack framerate set to 5 fps 1 multiplier Hey presto its much more responsive!!! It will be more jittery but just increase smoothing. See if it works for you... Edited by EDcase on 13/05/2009 at 13h18.

I get a feel that your camera loses or gets too weak signal from cap or there is too much inteference by outcoming light. I have old P4 2.8 with 1 gb memory and 9600 xt graphics card. With FT i use 3 point cap and MS VX1000 camera. And i run Arma with it. With this rig i easily get from FT steady 27-30 fps and practically no jitter (0-6). Have you forced your camera to outdoor settings? And have you sanded down the leds? Don't leave plastic more than 1 or 2 mm above the cathode. What colour the leds are? Hope u get some improvement out of these... Cheers, Snow Oh, and just remembered, A thing worth checking is that you have enough bandwidth in cameras USB line. (and that it supports USB 2.0) (edited typos) Edited by DrSnow on 11/05/2009 at 20h28.

Freetrack shows the camera operating at about 38fps raw. But when the camera is operating at 30fps in ArmA the head movement lags behind when I turn my head. My low fps settings make the head response MUCH better. After all you don't move your head 30 times a second so its not necessary to have the sampling so high. Thanks for the reply anyway.

Camera runs at 30 fps, with Multiplier 1. Eliminates almost all lag. Yes, I think the multiplier at 4 (auto) makes the movement smoother but very laggy/slow. Edited by EDcase on 18/05/2009 at 15h50.
