they definetly got rid of a lot the lag between toolpath tasks on larger files, that was a real killer i cant stand to wait 15-30 seconds for a window to come up
did a transform op in record time tonight, less than 20seconds it took 5 minutes before
the calculate speed feed button STILL DOES NOT WORK when you select a undefined type tool!!! WTF mastercam?
X4 MU2 has been the most stable release for me since X. I am hoping to see the same from MU3. So far so good. Prior to X4 MU2 I was getting some pretty consistent crashes due to a very unstable operations manager. I havent seen that in X4 at all since MU2. Some of the other minor bugs I guess I have just learned to live with or work around.
