Dropped frames can cause judder. When the engine takes too long to render a frame, the frame will be missed, causing judder. This can be mediated by using [[timewarp]]. While using timewarp to solve this problem works well in a rotational-only system, problems can a raise when positional / translational tracking is introduced. When using timewarp, moving objects such as an animated character can also cause judder. The notice-bility of the judder depends on the size and speed of the moving object.<ref name="ATW blog1">https://www.oculus.com/blog/asynchronous-timewarp/</ref>
