The disappearance of a charge-density-wave (CDW) transition in Lu(PtPd)In is thought to be closely linked to a maximum of the superconducting transition temperature in the system. We studied the superstructure and the phonon softening in Lu(Pt
Pd)In by means of neutron and high-resolution inelastic X-ray scattering. A full phonon softening at 
= (0.5, 0.5, 0) with the appearance of superstructure peaks could be clearly identified. The large tail of the superstructure intensity above the CDW transition indicates the importance of critical fluctuations.
