I know. But it's still surprising that nixxes/eidos worked on the game for years and their AO solution is worse form something that a (experienced) NeoGAF user threw together in external tool on a whim.
After seeing the state of no mans sky, you should definitely know how lazy devs can be.
But I'll give you a great example of how poor some of the effects are ingame, turn up your ingame AO and disable your TAA. Then walk around prague. Lets just say there's a massive reason that Temporal AA option is sitting there semi hidden and as a default "always on" setting.
