Timewarp works well in a rotational only tracking system. When positional / translational tracking is introduced, it does not work as well and presents a few problems.<ref name=ATW blog1">https://www.oculus.com/blog/asynchronous-timewarp/</ref> When timewarp is used with positional tracking, only the rotational change is reflected in the resulting image.

The positional change is ignored, causing [[judder]]. This is solved through the introduction of [[#Positional Timewarp|Positional Timewarp]]. | ||
Moving objects such as an animated character can also cause judder. The notice-bility of the judder depends on the size, number and speed of the moving object.<ref name=ATW blog1">https://www.oculus.com/blog/asynchronous-timewarp/</ref> Large and fast moving objects can cause very noticeable judder. | Moving objects such as an animated character can also cause judder.
