CST Broadband Frequency Interpolation

Has anyone spent time recently comparing the broadband s-parameter frequency sweep interpolation engines of 3D EM simulators like HFSS and CST?
I am trying to simulate a 15th order LPF implemented using coaxial elements. Due to the construction and design, the filter is very high Q.
However, I am finding that CST is having a really hard time interpolating the frequency response. Instead of just solving for a few frequency points across the band, CST is stepping through the band point by point (i.e. as if the interpolator is off).
Has anyone had a similar experience as I am? I want to believe that I am doing something wrong, that the program is not this bad, but the settings seem to be okay...
