NVIDIA Kepler Anti-Aliasing Called TXAA

A couple of days ago, we spotted an image that implied Kepler having a so-called new anti-aliasing algorithm, and now we know what it is.

According to HKEPC, the GeForce GTX 680 will offer TXAA, which grants image improvements comparable to 16X MSAA but at a much lower performance impact.

In other words, it will be 16X MSAA-level video quality with 2X MSAA performance drop, or less.

There will even be TXAA2, capable making graphics even smoother than 16X MSAA while affecting performance only as much as 4X MSAA.

Oddly though, the screenshot of the NVIDIA control panel shows FXAA instead of TXAA. The source makes it sound like they are different features, but things aren't totally clear to us just yet.

In addition to the new anti-aliasing, Kepler will bring Adaptive V-Sync, a smart frame-rate limiter that adjusts frame-rate when heavy 3D scenes lead to frame-rates below or above monitor refresh-rate.
