Sudden onset of crazy viewport lag..

Mathew O

Hi guys, as of about a week ago my unity has been suffering from a huge amount of viewport lag. I can move the viewport, take my hands away from the mouse and keyboard and watch it move into place at a very low fps. The most odd thing about it is that if I move around within an empty scene in my current project I can get a 100% GPU load and then move around in an empty scene in a separate project and get sub 20% GPU load.

There are 4 computers all using the project and only mine is suffering from this issue, one of which has the identical system specs to mine.

I have re-installed unity.
I have scanned my computer for malware etc
Other programs are fine (Maya, Blender, Zbrush and marmoset toolbag)

I'm utterly stumped, please help?

Try removing all your editor scripts and see if that helps. Then slowly add them back to find which one is causing the trouble.

i've also had something similar happen if you've got a broken shader assigned to any materials in the scene, however it seemed to only be happening with my video card, everyone else that had the broken shader wasnt affected
