It doesn't work for me either, I still have to move slightly left or right.

As for the amount of smoothing, I use a PS3 eyecam and have the frame capture rate set to 60 rather than 100fps (to match my Vsync) with very low smoothing values. The tracking is very smooth and responsive - I don't see much difference compared to my previous TrackIR 4 ultra.

Blackdog_kt, well spotted regarding the smoothing. I am playing around with this at the moment and am not happy with the lag. The reason I increased it in the first place was the jitter when zoomed in but it is no good this high. Will look at the smoothing percentage setting also, thanks.

I'll try and get hold of the PS3 eyecam - thanks for the tip, SEE.

Jimbop, if you have Vsync enabled (and probably do since you are using headtracking and don't want screen tearing) try setting the Multiplier to x2 rather than x4. With a 30fps webcam the smoothing will be computed for 60 frames and not 120 - that should reduce the lag - theoretically!

As far as I understand, with Vsync your only generating 60 FPS max so I cannot see any advantage in having a x4 multiplier of the 30fps that a standard webcam runs at. The smoothing algorithm has 90 copied frames to deal with when set to x4 and the game video is capped at 60........:confused:

Thanks, I'm confused too! I managed to find a used PS3 eyecam online - will let you know how it goes.
