**The problem**
When activating Proportional Editing with objects sized in centimeter range, the influence circle is way to big, out of the screen and you need to scale it a lot with scroll .
This is very slow with high poly meshes (500k to 1M triangles).
Adjusting the proportional size for small areas just shows 0.00.
The default influence should be initialized relative to screen size or to object size.
**Exact steps for others to reproduce the error**
Make a 10 cm cube.
Subdivide it enough to get 500K tris.
Try to move a face with Proportional editing on. (On the first try all elements would move)
After adjusting the Proportional size value for 1 cm or less of influence the onscreen value for proportional shows just 0.00.
