A switchable rendering system uses both instanced rendering and vector rendering in rendering a raster or vector graphic with a nested repetition. The nested repetition includes multiple levels of repetition and for each level the switchable rendering system selects instanced rendering or vector rendering to render the level. This selection is based on resource availability, such as using instanced rendering for a level when the current resource availability is sufficient to allow instanced rendering for the level, and using vector rendering for a level when the current resource availability is not sufficient to allow instanced rendering for the level.
