    when i added motion blur to my scene, it became very laggy for some reason.
    the shutter angle is 220 and the sample count is 8

    The motion blur post process requires an additional full scene motion vector pass, and the post process shader is itself relatively expensive. Your computer may not be powerful enough to use motion blur on top of your existing game.

    Bgolus is right. Those type of effects are intensive.
    Try lowering down both the sample count and shutter angle.
