Hello @Crazybone992 and @KaoticSyndome
Sorry to hear that you're experiencing issues with the speed of the skills preview videos in Assassin's Creed Valhalla.
After investigation, the development team has confirmed that they are unable to continue looking for a potential fix for this particular issue as they must focus on issues that have a comparatively higher impact on the gameplay experience.
I understand that this is not the outcome you were hoping for and can only apologize.
In the meantime, if you have any other questions, feel free to ask and we will do our best to help you !
