Item #2: The video tutorials (yes, the game has in-game video tutorials) stutter on some (but not all) older video cards. This is due to alpha blending. You can turn off anti-aliasing but that may not fully solve it. We plan to have this dealt with by release day.

My video tutorial are stuttering.
I guess that means I have an older video card.
Its release day - so any update on this?
Strangely enough when I play the videos using that video player, there is no problem.
