Question: Hey Justin, for my gui-library I need to prevent Retina-upscaling since I have my own scaling-engine. How do I turn off Retina on Retina computers? gfx.ext_retina=0?

    gfx.ext_retina=1 on initialization. then, from that point on, you'd want to render with your own scaling, using gfx.ext_retina as the scalefactor. e.g. if it is 2.0, you should use fonts that are double the size, etc. does that make sense? and additionally, on Windows/linux, it will get set with the effective scaling.

    So, if I understand correctly, it's not possible to turn Retina-support off? I basically just want to have on all systems the same behavior as on non-Retina systems.

    If you set gfx.ext_retina=1 and then subsequently ignore it, on macOS retina displays everything will be tiny and high resolution. is that what you mean?
