Laggy Animarion Render (Need help/advice)

Hello! I was just rendering why everytime I render a 1920 x 1080 animation, it’s laggy? No matter how simple, if it’s some cubes falling or a wall being knocked over, the animation is skippy. I was wondering if there might be something behind this, or if it’s simply my hardware. Thanks.

What codec did you render to ?
How are you playing the animation ?

or if it’s simply my hardware
Which is what ?
