when you say "too quickly" are you referring to the "noise" I guess.
If it is the case, you could try to filter you xtc either with g_filter 
in order to reduce the fluctuactions or in vmd itself you can smooth the 
xtc in the graphical representations -> trajectory tab -> trajectory 
smooting (2 or 3 should be enough)

hope it helps
