Up until yesterday Unity was working fine, but now there is about a 6-8 second wait when switching windows for me to be able to then interact with objects within that window. For instance, say I've just done something in the inspector and click the scene view. I click, wait 8 seconds then have full, lag free use of the scene view. But then have to repeat that process when clicking onto another editor window. This is the same for all projects no matter what version of Unity. After looking online I've tried the following - Forcing opengl - Updating drivers - Switching to DX9 in player settings All to no avail, so I'm open to any suggestions as to how I might get around this problem. Again I've never experienced this issue until yesterday, no errors, no warnings. Created new projects, same problem. Nothing out of the ordinary in Task Manager either.
