The headline feature of 4.03 is optimization. Stardock claims a 40% reduction in CPU usage for animated cursors running at 144Hz or higher. In real-world testing, a complex animated cursor (such as the popular "Neon Pulse" set) previously consumed 4-6% of a mid-range CPU. Under 4.03, that same cursor uses just 1-2%.
