My experience with the VEP 6 upgrade has been terrible. I have a large template on a super fast Windows 7 host that used to run at 10%, spiking to 25% with VEP 5. Now, with VEP 6, the template averaging 35% and spiking to 100% (and dropping audio). Load times have gone from about 3 minutes to close to 10.
I'll be uninstalling it later today, but I'm curious if anyone else has had such a poor experience. The 6.0.15318 maintenance upgrade didn't help the issue.
