ar_track_alvar running too slow(~1hz)

I am using a logitech c920 to detect a marker. I am running pr2indivnokinect launch file of the artrackavlar ros package. But the thing is only running at 1hz. In the node file, it says there is a parameter called maxfrequency which is already set to 8.0 and I tried to set it to 30 but nothing changed. Anyone know how to get it to run faster?

What hardware are you running this on? And what is the resolution of the camera images?

ar_track_alvar should run over 20 hz easily on most PC's these days.

The answer here worked for me:

I.e adding <param name="max_frequency" type="double" value="10" /> to the node tag in the launch file allowed me to control the publication frequency of ar_track_alvar.
