GTX 680 Supports New AA Algorithm (TXAA), Adaptive V-Sync, and More

Some new features are going to come out when Kepler rolls around. The first new feature is a new algorithm to smooth out the jagged edges associated with polygons AKA anti-aliasing. The new method of AA is called Temporal Anti-aliasing or TXAA. The new AA technique can deliver a quality of 16x MSAA at a performance cost comparable to using 2x MSAA. In addition, 2x TXAA can deliver above 16x MSAA quality at a performance cost comparable to using 4x MSAA. So, there will be two options for TXAA, which are 1x TXAA and 2x TXAA. Upon its release, not every game will support TXAA, but a quick work around is to force TXAA via the Nvidia control panel.

Next, adaptive v-sync will not only prevent screen tearing, but this new feature allows the GPU to dynamically enable or disable v-sync depending upon the system’s performance. In other words, if your frame rate goes above or below your monitor’s refresh rate the GPU will turn v-sync on or off accordingly. The functionality is depicted in the graphics below.

Finally, a single Nvidia graphics card will now support up to four monitors . This means a single GPU can support 3D Vision Surround setups. Adaptive V-Sync can also be enabled in such configurations.
