This improves performance of some sculpt tools, particularly those that modify many vertices like filter and mask tools, or use brushes with large radius. For mask expand it can make updates up to 2x faster on heavy meshes, but for most tools it's more on the order of 1-1.1x. There are bigger bottlenecks to solve, like normal updates.
