Nothing is more distracting than framerate stuttering and screen tearing. The first tends to occur when framerates are low, the second when framerates are high. Adaptive V-Sync is a smarter way to render frames.
At high framerates, V-sync is enabled to eliminate tearing, at low frame rates, it’s disabled to minimize stuttering. It gets rid of distractions so you can get on with gaming.
Many gamers enable Vertical Synchronization (VSync) to prevent screen-tearing, an unsightly occurrence caused by frame rates exceeding a monitor’s refresh rate. The downside is the occasional and equally annoying stutter when frame rates drop below the locked VSync frame rate, and again when they return to the locked rate.
To fix the problem, the GeForce 301.42 WHQL drivers come loaded with NVIDIA Adaptive VSync, an automated technique that disables VSync when frame rates fall below the locked rate, and re-enables it when they return to the locked rate, significantly reducing stuttering whilst still preventing tearing.

Back in the day, we have informed you about a new feature of nVIDIA called TXAA and no Linux support. Well, after the 304.43 release now you are able to use this technology since you are using modern nVIDIA card and their proprietary driver in Linux/Ubuntu 😀 To enable FXAA under Ubuntu, open nvidia-settings, go to Antialiasing Settings and check the “Enable FXAA” option.
