Hi.
I'm using MacOS 10.9 and SFML 2.1 on a MacBook Pro (NVIDIA GeForce GT 750M) with retina display (2560x1600). SFML only lists me video-modes up to 1680x1050 and it looks like the window gets scaled up about twice in size. Even the system-specific window-buttons to close or minimize the app only show in half resolution compared to all other apps.
I don't have such issues with other games. For example Diablo 3 always has the correct size and even allows retina resolution.
Any ideas what's going on? The SFML-sample-applications or Xcode-Templates behave the same by the way.
