Thanks for the information, I kind of figured that out when I finally made a short test video.

So far, it does seem to run faster and do some things better than the earlier versions.   It seems to me that it handles shadows better in Preview mode, which is a big factor for me because I never render anything that is going to be video.  I usually had to turn them off, but they seem to look pretty good on the few things I've done.

I figured out a long time ago that rendering things in preview mode at high resolutions is much faster than actually running them through a render engine.

Once they are reduced to the size you want or in my case I leave them at 3440 by 1440, so they are full screen on my monitor, they look nearly as good and in a fraction of the time. 

Now it's time to do a test with speech and run it through my editor and see how it goes. 

If you shoot a mime, do you need a silencer?
