Option to switch off the undo feature

just updated to astarpathfinding 3.6 + unity 4.6
It is very slow in my large project.

Hi

You can switch off the undo feature by going to Settings -> Editor -> Undo = false.
Are you sure it is the Undo that is causing it and not e.g gizmo drawing?

Also, if you have been using cached startup, make sure you have transferred the data to a separate file (open the Save & Load tab and follow the instructions there, if there is cached data you will see a button and some instructions).

I can’t see the setting

Hm… I must have removed it some time ago.
Are you really sure that undo is causing the performance problems?
I see that you have Show Graphs enabled. That is more likely to cause the slowdowns.

the slowdown is caused by other 3rd party plugin, sorry for the reporting.

Ok, great that you managed to solve it.
