but the biggest change of all is that 90% of the GIMP’s core uses GEGL. At first I thought that since I have a crappy GPU, this wouldn’t mean much, but it does. GIMP seems to be almost double as fast. Simple filters like blurring is much faster. Many filters like the sharpening filter rely on the blurring filter. Many complex filters including 3rd party filters are much faster, as they are now using GEGL technology underneath. Another great thing about GEGL, is that it brings us one step closer to 16 bit images.
