Display/scaling issues on Macbook Retina + Windows Bootcamp

[Lightloch]

Searched and found somewhat related posts but didn't find anything very specific on this.

I installed P99 a 15" Macbook Pro Retina running Windows 8.1 Pro via Bootcamp. All drivers installed and working properly. When I run P99, no matter what in-game resolution I use, the text is garbled to the point it is basically unreadable. I have also tried adjusting the actual Windows resolution to no avail.

The only thing that sort of works is changing both the Windows and in-game EQ resolution to 1366x768, but the lack of window space in EQ and massacre to the Windows UI is pretty unbearable.

Any recommendations?
