Can you think of anything that changed between when it worked fast and when it doesn't? e.g., document size, brush size, any other settings? Did you recently install or remove anything on your computer? Conversely, can you get it to work fast by changing document size, or having the same configuration on a different machine?

I've been working on a terrain and left off for a couple of weeks. Now, after returning to it, it's not performing the same way. The update is extremely slow. I've tried brush continuously but it's still the same. The lighting setting are set on quickest. I'm working soley in the 2D pane.Any ideas what it could be? Carl
