Unity 4.5 Performance

I’ve notice that since I installed 4.5, my computer fans are totally taking off, even when the program is in the background. This was never the case before, even when in Play mode. If I click X (Exit button) the save dialogue pops up and instantly the fans slow down to normal speed.

Is anyone else experiencing this?

My fans are churning so hard I think I can use my tower as a makeshift helicopter.

Is this even in a blank new project?

This I haven’t tested. Get back to you soon.


It doesn’t seem to happen in a new project, at first glance, but it did happen in a very, very basic project, upgraded from 4.3.4.

I’m going to do more testing when I have a chance and pin down when this is triggered. Its quite sporadic, but it’s definitely Unity and not some other program causing this.

(Maybe somehow the times when the editor won’t Quit are linked).
