You have to declare that the app is "DPI aware" in the manifest and implement few things that go along with that promise. Just google it, it's fairly simple.

While I got you here, can I ask how many people worked on this and how long did it take? Just curious.

You should be able to simulate one by clicking "make text look larger or smaller" in screen resolution.

At Screen Resolution -> Make text and other items larger or smaller you can set the DPI to other value (ex. 125%)

This is the information for DPI-Aware applications.

I would attach some source code from a game I wrote, but I don't have the source code of it at hand right now.

Running Windows 8.1 on Macbook Pro Retina (via bootcamp). I found this on MSDN...not sure if it's applicable: http://msdn.microsoft.com/en-us/library/windows/desktop/dn46...

Came to say the same thing. This is while running it on Windows 8.1 through Parallels 9 on a rMBP.

I'm seeing similar behavior on a Surface Pro 3.
