For people interested in font rendering in current browsers, which has really gone downhill due to how horrible the font rendering in Blink based browsers on Windows is, and especially given that we’ve recently lost the possibility to even disable DirectWrite in Blink browsers completely, it might be worth noting that after three years, there’s finally been a new MacType release yesterday that also introduces the possibility to tweak DirectWrite behaviour.
In case you don’t know, MacType is (somewhat contrary to the name of the project) an application that basically replaces Windows ClearType with FreeType, a font rendering engine that’s mostly used in Linux (and which in my opinion is absolutely superior to ClearType/DirectWrite and is also much more tweakable). It doesn’t offer the same amount of customizability when it comes to DirectWrite as it offers for general Windows font rendering, not by a long shot, but you can still tweak it a bit.
