But in your case it seems that there is an animation pack~
And then check the game settings, is the quality of the graphics adjusted too high, if so there will be a situation like yours~
I don't know what the display device is on your machine, if the graphics card is not too good then turn down the various graphics options a little bit~
And also windowed mode will take up less resources when playing the game.
