Assassin's Creed Director's Cut freezing

Recently I decided to download Assassin's Creed Director's Cut and while I am playing it will freeze for a few seconds and then the game is unfrozen. My PC meets the minimum and recommended system requirements for this game and I have no clue why this happens. I used both DirectX 9 and DirectX 10 but still they did not work as it still happens regardless of the DirectX version. Can anyone please help me solve this issue and thanks in advance.
