Have you tried to set it at lower resolution or with lesser details? Maybe your computer can run older games at maximum details and resolution, but it cannot handle with Vanguard. Your animations problems are easily avoided if you set your graphics at lower level. On the other hand, if you do not want to do those things, you can buy new graphic card, new and faster processor and more RAM. Even so, I think that setting graphics level at lower value will be smarter solution. In both cases, you will be able to play Vanguard with better graphics. It is up to you.
