Vivacity is its own suite of filters which are basic tools. It has a few extra functions, such as sharpen, enlarge, and smooth and curly type of effects. The noise reduction in Vivacity is not as good as DeNoise, which uses our newest algorithm.
The programs included in the bundle are full programs that offer additional tools and features. If you own the bundle then most likely you will not need Vivacity, unless you have the need to Enlarge. Also, the bundle is 64-bit CS4 compatible and CS5 compatible. Vivacity is not.
