Things are pushed around, getting knocked to the floor or kicked halfway through the room all the time. The interaction between the dragonborn and all objects in the game is driving me insane! How can i turn this off?

I can't understand why Bethesda made this so incredible unrealistic. I mean i sometimes knock things to the floor in real life, but in Skyrim it looks like a battlezone everytime im indoors just for a few seconds. Even Npcs are messing everything up and kicking things around aswell.

Is there anyway to change this?

Are you running the game over 60FPS if so that could be part of the issue. The game physics can get wonky when running that high of a FPS.
