Except for a bug when editing light settings (e-on has said it will be fixed), I have not had any of the above mentioned problems with the final release.  My system resources are staying stable and things are working very well.  The only time I see a slow down is with one file that uses a volumetric atmosphere.  That scene gets painfully slow to move things around.  Change the atmosphere and it goes back to normal speed...  Don't know if that is a bug or not, but so far I am happy with the final release.  

I'm not sure it a widespread dissatisfaction, those who are happy with Vue are not as likely to post as those who are unhappy...
