Short description of error
The performance of the cloth brush seems to have regressed from 2.90.1 to 2.91.0.
Exact steps for others to reproduce the error
- Subdivide the default cube to 1.5mil vertices (likely dependent on your systems capabilities) and apply.
- Go to sculpt mode and select the cloth brush.
- Draw a stroke and compare performance.
