Plug-and-Play Tessellation

NVIDIA Plug-and-Play Tessellation is an advancement of what used to be GeometryWorks. The Tessellation libraries and tools that NVIDIA has put together allows for developers to greatly enhance the amount of details the players see. With these libraries it is relatively easy to add tessellation to the AnvilNext game engine, allowing to quickly generate tessellation displacement maps suitable for tessellation from pre-existing objects in the library. The library also intercepts DirectX draw calls, analyzes the vertex shader currently being used, and adds its own tessellation shaders, so developers can simply add to the displacement map generated by the Displacement Map Tool.

Tessellation allows what would normally be a single, flat texture that does not alter the lighting, or shadowing of the game to become a single “three dimensional” structure inside the game to which HBAO+ can shadow correctly and affect how PCSS casts over the area. The addition of geometrical detail plays a key role in this, and is what NVIDIA has been working on for quite a while.

In Assassins Creed Unity, Tessellation has not yet been released as of the moment of writing this article, however NVIDIA has confirmed that it will bring GeometryWorks DirectX11 with a later update.

    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.
