Window selection performance on MS Windows

Tuesday, January 6th, 2009

As this software started out as a Windows program it used to draw the rectangle the “windows way” (using a device context). This didn’t work on macs and probably not on future linux version either. The remedy was to use OpenGL methods instead. Performance on my first generation Mac Mini was excellent so I didn’t think more about it. It turns out that some ms windows drivers are way pickier and on some PC’s, performance was terrible. I’ve restored the old method to the windows platform, this will be fixed in the next beta release.
