Description (last modified by historic_bruno)

It would be nice if 0 A.D. could take advantage of Hi-DPI displays, such as Apple's Retina displays.

As far as I can tell, this requires the following:

  • Upgrading to SDL2, which adds the SDL_WINDOW_ALLOW_HIGHDPI flag
  • Ensuring the GUI remains at the original size (i.e. magnifying it by 2x with respect to 3D graphics)

And the following are nice-to-haves:

  • Doubling the resolution of the prerendered fonts for crisp text rendering
  • Providing all bitmap graphics in double the resolution (seeing that 4K displays are on the horizon, perhaps new bitmaps graphics should be prepared at 4x the resolution)

I've attached a simple-minded patch for the first issue (SDL2 support) to ticket #2041, and I've prepared a patch to address issues 2 and 3 (scaled-up GUI and high-res fonts), will attach it shortly.

SDL2 support has been merged into SVN. It's not yet the default for OS X, but will be for A17 and this task can be worked on.
