Heavy FPS drop when using the Sculpt Terrain Tool

Hey Developers!

Currently have an issue whenever I am using the Sculpting Terrain Tool, when I use the tool I experience heavy performance issues and sculpting takes forever to use. When I use other tools, such as the draw tool I have no performance issues.

I have a pretty good computer so I don’t believe this is an hardware issue. I have tired this on an empty baseplate and the issue is still there. Any guesses on how to fix this?

I have same issue when using large brush size like 50+ , maybe because it reloads vortex of terrain.

I don’t think there is way to fix that except reducing brush size to be like 10-20.
