VAB freezing

[Kram45]

Ever since I updated 1.5 my large craft freeze for a few seconds every time a part is added. CPU sits around 40% while in use and shows no spike when the freezing happens. I believe it is due to the high part count but I never had this problem in older version. Any help?

Edit: I have a completely vanilla install.

Try giving this mod a whirl:

You might have to wait a little bit for @linuxgurugamer to update it (check his massive list of mods he has to update for it's status) to 1.5, but it might fix your issue.  Maybe not, but it can't hurt to try.  I know you're running stock, but I really don't consider mods like this to be a "not stock" game. 

You can also can try upping the priority of the KSP.exe in the Task manager in windows, that might help some. 

How's your RAM usage look?  Does it do it with just high part counts, or when you are just starting a build too?
