Ubersampling is a wasteful form of antialiasing, as are all other brute-force methods, and excessive antialiasing creates artifacts that are no less objectionable than the jaggies.
What they really need to do is make the game play nice with a variety of AA technologies, not just Ubersampling, MSAA, or TXAA, but injectable technologies like SMAA.
Shhh! They have to justify their 4xTitan.
