A method, apparatus and computer program product for parallel speculative rendering of synthetic images in an image rendering system are presented. The operations include obtaining measurements regarding scene characteristics. The measurements are provided to predictors, each predicting a future state for a measurement. The future states are provided to a renderer that renders graphical entities, each rendering resulting from a different predicted future state. Subsequently, a new set of measurements is obtained regarding the scene characteristics. Then each measurement of the new set of measurements is compared with a corresponding one of the predicted future states produced by the predictors. The predicted future state that most closely matches with the new measurements is then selected. Then, the graphical entities associated with the predicted future state that most closely match with the new measurements are selected. The selected graphical entities displayed on a display device.
