I don't know of any hinting technology which cares about DPI.  But,
TrueType fonts usually contain delta hints which adjust glyphs at specific
pixel sizes. The set of pixel sizes so hinted is generally small, and
limited to what is likely to appear in a typical Windows environment.

What you're likely seeing is the difference between a size for which delta 
hints are available and a size at which only the general hints are used.

This suggests that "typical" point sizes would be best rendered if they
mapped to the same pixel sizes as they do under Windows.
