Lag while editing with new LR update

[jenniferv33521144]

I'm finding that my brushes are causing lags/spinning wheel in the new LR update.  It's really slowing down my workflow.  Any advice?  Is anyone else having this issue?

Make sure that your GPU usage is OFF. (Preferences->Performance->Use Graphics Process is set to OFF)

If that doesn't help:

Given the number of reports of slowness on MAC with LrC 10.0, I would suggest you re-install LrC 9.4
