I just tried the trial version and there is a nice new feature that shows the selected timeline clip length at the bottom of the timeline which updates live when while making length adjustments to the selected clip. Been waiting for that one for a long time.
I don't know why you are having problem with the link. I just log off and get back on the forum without login, click it and it open just fine for me. I am using IE. Any way, the link screen shot shown both VP11 and VP12 rendering performance is about the same, on my system. I can't say the same for others.
