An apparatus for fast inking a touch display is described herein. The system for fast inking a touch display can include receiving touch input and generate touch sensor data. The system can include agraphics processing unit (GPU) including a fast inker and a display pipeline. The GPU can transmit human interface device (HID) data generated from the touch sensor data to a writing application memory and the fast inker. The fast inker can convert the HID data into inking data to be sent to the display pipeline through a direct hardware path. The writing application can convert the HID data intoinking data to be sent to the display pipeline. The system can also include a touch display to display pixels marked according to the inking data received by the display pipeline.
