yes i think the issue is the new travel system if you disable "Find travel routes" you should see an improvement in framerateQuote:
Disable the internal waypoint module and use Tomtom, much faster, gets rid of the slowdown till zygor fixes their internal waypoint module.
In addition, Whoknowsit, Please don't shut down this project. I and several other people appreciate what you are doing.
sadly the travel route thing is going to be important leveling on ground mounts!
EDIT: actually it isn't the travel routes themselves but the ANTS option, which you can disable completely while still keeping the travel routes
