# loversize parameter from lettrine package not working

The loversize parameter from the lettrine package is not working for me. Below is a MWE to illustrate the problem:

\documentclass[a4paper,12pt]{article}

\usepackage{lettrine}

\begin{document}

\lettrine[loversize=0.5]{T}{his} is a sample of text. This is a sample
of text. This is a sample of text. This is a sample of text. This is a
sample of text. This is a sample of text. This is a sample of text.
This is a sample of text. This is a sample of text. This is a sample
of text. This is a sample of text. This is a sample of text. This is a
sample of text. This is a sample of text. This is a sample of text.
This is a sample of text. This is a sample of text.\\

\end{document}


Setting loversize equal to any decimal value in the permitted range (from -1 to 1) does not change the dropped capital in any way. Does anybody know why this is the case?

\usepackage{lmodern}
