Add rooftop elevator, lounge, volumetric city, river and animated traffic. Prune invisible mesh faces, clip CPU surfaces, streamline compositing and add automatic/F8 roof quality profiles with renderer diagnostics. Include dartboard/reticle improvements, tracked fortune orb numerals and fate-session visuals, native regression tests, compatible jukebox IDs and updated shipping executables.
