Provided are a graphics processor that performs warping, a rendering system including the graphics process, and a method of operating the graphics processor. The graphics processor may include an internal command generator and a graphics computing device. The internal command generator may be configured to receive timing information and generate, based on the timing information, a warping command for periodically performing warping. The graphic computing device may be configured to, in response to the warping command, periodically perform the warping, without a context switch by a host, by using sensing information provided from an external source and frame data that have already been rendered.
