NEW: Efficiency Mode!
Storyboarder now has two drawing modes: "High Quality" (the default) and Low Quality “Efficiency Mode”, which is not “worse” but just “better, in a different way”. Efficiency Mode will run much, much faster on older computers, but it won't take advantage of the new advanced brushes we added for Storyboarder 1.6. Brushes in Efficiency Mode look kind of like the simple brushes from older versions of Storyboarder.
To try out Efficiency Mode, visit Preferences, and disable the "High Quality Drawing Engine".
