NVIDIA announces Adaptive Ray Tracing Temporal Antialiasing for games

NVIDIA has announced a pragmatic algorithm for real-time adaptive supersampling in games that extends temporal antialiasing of rasterized images with adaptive ray tracing, and conforms to the constraints of a commercial game engine and today’s GPU ray tracing APIs.

What this basically means is that this new Adaptive Temporal Antialiasing will address the blurring and ghosting issues that are introduced with TAA.

As NVIDIA noted:

“The algorithm removes blurring and ghosting artifacts associated with standard temporal antialiasing and achieves quality approaching 8X supersampling of geometry, shading, and materials while staying within the 33ms frame budget required of most games.”

Unfortunately, this new anti-aliasing technique may not come to PC games anytime soon. After all, there isn’t any gaming GPU that can support ray tracing right now (though this may change next month).

Either way, this is another technique via which NVIDIA – and perhaps Microsoft – will use ray tracing in video games!
