Bad Subdivision Performance in 2.8 Beta
Closed, ArchivedPublic


System Information
Operating system: Windows 10
Graphics card: Nvidia 1060

Blender Version
all current 2.8 versions
Worked: 2.79b

Short description of error
Strangely poor performance when adding, editing and deleting subdivision modifier. On objects with 15+ booleans, it takes like 15 seconds to add 1 iteration of smoothing. On scenes with 4M+ faces, subdividing a simple sphere takes ages. Performance was excellent in 2.79b

Exact steps for others to reproduce the error
Create spheres with subdivision surfaces and duplicate until around 4M faces. Enjoy poor mesh mode performance.
Create an object with around 20 boolean modifiers. Add a subdivision modifier.

Note however there are still some missing features and performance problems in the new implementation. Particularly animation playback and moving of vertices in edit mode will be improved before the final 2.80 release, to bring it back to 2.7x level.
