love.window.getPixelScale

Available since LÖVE 0.9.1
This function is not supported in earlier versions.

Gets the scale factor associated with the window. In Mac OS X with the window in a retina screen and the highdpi window flag enabled this will be 2.0, otherwise it will be 1.0.

The scale factor is used to display graphics at a size the user is expecting, rather than the size of the pixels. On retina displays with the highdpi window flag enabled, the pixels in the window are 2x smaller than the scale of the normal content on the screen, so love.window.getPixelScale will return 2.
