The present invention relates to a prediction system for determining a set of subregions to be used for rendering a virtual world of a computer graphics application, said subregions belonging to streamable objects to be used for rendering said virtual world, said streamable objects each comprising a plurality of subregions. The prediction system comprises



a plurality of predictor units arranged for receiving from a computer graphics application information on the virtual world and each arranged for obtaining a predicted set of subregions for rendering a virtual world using streamable objects, each predicted set being obtained by applying a different prediction scheme,
a streaming manager arranged for receiving the predicted sets of subregions, for deriving from the predicted sets a working set of subregions to be used for rendering and for outputting, based on the working set of subregions, steering instructions concerning the set of subregions to be actually used.
