Also note that GTK's widget drawing is handled through the theming engine. The built-in theme for GTK2 is almost pure core drawing routines, whereas every other theme uses more render paths and so not only looks less ungainly but also benefits from EXA much more. GTK3 further favours EXA. But it is difficult nigh impossible to go from gtkperf to determining impact upon application usability.
