OK, this is my last update until I return on the 5th, heading out for a BIG 4th of July weekend with friends and family.

Update -

Here is the time it takes to render the scene linked to in my first post, using the "Final" settings, in just the standard size view port window:

WITH the cloud layer added in the "Cloud" tab in "Atmosphere Editor" -

Windows 7 RC - 46 Minutes to finish.

Mac OS - Not possible so far.

WITHOUT any cloud layer in the link above but same scene otherwise -

Windows 7 RC - 7 seconds

Mac OS - 12 seconds.

Obviously there is some sort of strange issue going on and we are still working on it. Once I get back I will report any updates from them or other findings.
