Nvidia shows edge smoothing with ray tracing

Earlier in the year, a number of players demonstrated different bottlings of ray tracing, or beam tracking, which will take realistic game graphics to the next level. During this year’s edition of the GDC trade show, Nvidia introduced the RTX technology, which is a hardware-accelerated method for implementing real-time ray tracing for gaming.

The company now announces that it has joined the Temporal Antialiasing (TAA) anti-aliasing technology with RTX, which improves the precision and realism of the processed images. Nvidia calls the new method Adaptive Temporal Antialiasing (ATAA) and several of its predecessor’s problems should be gone. An example is edge smoothing of images with a lot of movement.

According to information, ATAA is a method designed for use in just games, and in the game engine Unreal Engine 4, the company has measured improvements that correspond to downscaling from an image with eight times higher resolution (English.

The test was performed with the Volta-based graphics card Geforce Titan V under the hood and the resolution 1,920 × 1,080 pixels, which resulted in the rendering times falling below 33 milliseconds per image. This corresponds to a refresh rate of 30 FPS or higher.

RTX and ATAA are still in their infancy and are not compatible with any of the market’s consumer-oriented graphics cards. Nvidia’s methods will then primarily work with its own software framework Gameworks, but also Microsoft’s newly launched graphics interface DirectX Raytracing.
