Parametric modifiers Performance: 3ds Max vs Blender vs Houdini

A comparission with a parametric modifier over a 3d scan in Houdini, blender and 3ds max. The scan has 2M polys. Plays fluid in 3dsmax (15 fps) Houdini around 5fps. Blender doesnt reach 2 fps at any point. About interaction, is difficult to see on video, 3dsmax is totally responsive. Houdini is not so bad, with some lag, but workable, Blender is in this case a disaster with a huge lag.
