There's two steps to using the hires mode on OS X. First, you need the OpenGL configuration to be in hires-mode.
Second, you need to set the viewport in your OpenGL code to the result of `get-gl-client-size`, not `get-scaled-client-size` or `get-client-size`, which are all very similarly sounding functions. -- Jay McCarthy Associate Professor @ CS @ UMass Lowell http://jeapostrophe.github.io Vincit qui se vincit. -- Jay McCarthy Associate Professor @ CS @ UMass Lowell http://jeapostrophe.github.io Vincit qui se vincit.
