Windows OpenType CFF Font Rendering

We have a situation where our identity font is displaying terribly in Microsoft 2010 on Windows 7. The font looks great in InDesign and Illustrator. The font family is OpenType with PostScript outlines, aka CFF. This behavior is consistent for any OpenType font from Adobe, ie Myriad Pro or Adobe Garamond.

I am nearly certain that the Windows font rendering engine is optimized for TrueType outlines and renders PostScript outlines poorly. I also think that Adobe is using a different rendering engine for the Creative Suite applications, perhaps their own. I have not been able to find any specific documentation of these statements.

Does this ring true? Does anyone know of specific documentation of poor font rendering in Windows applications, especially MS Office?

CFF format


I was searching Adobe documentation to see if anything important's been updated since... 1996 and I became so put-off by the composition of the PDF describing the Type 1 format..

...I had to stop.

Does anyone know, does CFF still require that "sub-paths" do not overlap, (just like the faces of hot metal faces), and does CFF still demand a 1,000 unit em?
