NVIDIA TXAA

When NVIDIA released TXAA, they were trying to reduce temporal aliasing which produces crawling and flickering in motion during gameplay. TXAA is a mix of the already known Multi-Sample AA (MSAA) along with a custom CG film style Anti-Aliasing  and a temporal filter. To correct the sharpness of each pixel structure, TXAA gathers samples from inside and outside the pixel as well as samples from other frames to filter each pixel. This greatly improves the spatial filtering over the standard MSAA filtering and can be clearly seen on objects such as fences and foliage.

Another improvement over FXAA, is TXAA’s capability to intelligently manage per-pixel effects (such as atmospheric rendering) without introducing weird lighting artifacts on structure edges. What is interesting, is that in motion scenes, TXAA can be compared to other high end professional AA algorithms that are usually not available for end users today, but rather on the enterprise hardware from which TXAA was developed from.

As you may notice the differences per frame between TXAA, FXAA, and 4x MSAA are almost minimal, however TXAA brings the added benefit of reducing temporal aliasing when in motion throughout the game. The performance impact of TXAA is also different as it varies depending on the type of shading between each game. During our Assassins Creed Unity test we noticed that the performance was relatively similar to that of FXAA.

    Looks good on paper but, Nvida held back on their top GPU just like with the 600 series was launched. 1600p and 1440p seem to be the new standard ans 4k g-sync mentors have hit the market. Who will get to fully experience all these things in an enjoyable manner? I’ve only owned Nvidia cards since 2007, i’m not trolling and i’m no fanboy. I’m a 40+ enthusiast who is waiting for Nvidia”s true next gen card. The gtx 980 isn’t much of an uprate compared to the 780 ti and the 970 are roundly equal to the regular gtx 780. Is G-sync is aw some but wont help much at 30fps , the 1440p Asus swift has been out of stock since September and the Acer equivalent s due Q2 2015.

      The Asus monitor that you are talking about is 800 dollars. My thinking is that it won’t be much of a problem for someone who plans to spend 800 on a very specific monitor like the Asus, and they will indeed be going at least 2-way SLi with 970’s or 980’s.

      The GTX 980 and 970 are right about where you said they were in performance, yet are low cost solutions to the 780 Ti, and 780 respectively. All while maintaining the same performance (slightly higher usually) and adding an extra 1 GB of frame buffer, along with the extra features in the Maxwell architecture.

      The games optimized correctly to take advantage of Maxwell are going to see performance gains even more so over the older 780’s that do not include the features Maxwell does.

      Waiting for the ‘better’ Maxwell’s is a personal choice and if you are not in need of a new graphics card, waiting is always going to pay off since new cards are always improving upon previous generations.

      So, to enjoy all these features in an enjoyable manner, it all depends on how much a person is willing to spend, and how well they match their hardware to the task at hand. I don’t think anyone is going to invest in an 800 dollar 1440p monitor and not get the necessary hardware to make it functional and enjoyable.
