Wrapping NV_path_rendering is on my wishlist, slightly ahead of wrapping d2d and both ahead of taking the best ideas for a cairo protocol. (NV_path_rendering is a very good spec to base a path protocol on.) Note that NV_path_rendering only deals with paths (albeit can be passed though paths in both SVG and PS/PDF formats), you still need to setup and manage patterns, which is where leveraging the exisiting Cairo infrastructure will help. My experience would favour Nvidia over AMD, and for your suggested workload a UMA over discrete GPUs. But benchmarking is in the eye of the beholder. -Chris -- Chris Wilson, Intel Open Source Technology Centre -- cairo mailing list [email protected] http://lists.cairographics.org/mailman/listinfo/cairo
