Choppyness, no hud, strange lines (JENS TAKE A LOOK PLEASE)

Maybe we should fix the physx problem first as it might be causing problems to the driver. Uninstall the nvidia drivers and restart. Run driver sweeper. Select all nvidia options and remove everything found. Restart and re-run driver sweeper in case something was left. Now install the drivers again and make sure to select clean install. It should install everything normally.

Update 1.2 should and most probably cannot cause such problems. In general, can you install the game and leave it without updates from steam just to see if it works that way?
