'''Timewarp''' also known as '''Asynchronous Timewarp (ATW)''' or '''Time warping''' is a technique in [[VR]] that warps the rendered image before sending it to the display to correct for the head movement occurred after the rendering.<ref>https://www.oculus.com/blog/asynchronous-timewarp/</ref> Timewarp can reduce [[latency]] and , increase or maintain [[frame rate]] and reduce [[judder]].<ref name="YT1">https://www.youtube.com/watch?v=WvtEXMlQQtI</ref> This process takes the already rendered image, modify it with freshly collected positional information from your [[HMD]]'s sensors, then display it to your screen. Utilizing [[depth maps]] ([[Z Buffers]]) already present in the engine, Timewarp requires very little computation. Additionally, Timewarp reduces the effect of [[judder]].<ref>https://www.oculus.com/blog/asynchronous-timewarp/</ref>
