Xara LX has always been the fastest drawing and illustration tool available. Common operations such as rendering, loading, saving and general editing are typically many times faster than other software, in some cases ten times faster. Xara LX is now even faster still. It all makes for a more slick, smooth user experience and the ability to create more detailed, more complex art, faster.
Speed on its own is not enough. The Xara LX user interface is generally regarded as the simplest, cleanest, easiest to learn. That's why it's loved by artists the world over.
