Is it possible to only run one application as non-retina whereas everything else is retina? I have a Macbook Pro Retina 15" (Mid 2014). For whatever reason I noticed that one application (Netbeans) is a lot faster (the interface) when it runs in a non-retina screen (noticed this when I connected a second non-retina display).

I don't really like using a second display. And I also really like the retina graphics. Is it possible to only run one application (Netbeans) as non-retina whereas everything else is retina?

OSX Yosemite 10.10.5.
Select Netbeans in Finder, right click and press "Get Info" (or press Cmd ⌘-I on the keyboard). In the window that pops up, check "Open in Low Resolution".
