NVIDIA is working to improve GPU light tracking performance: up to 20% higher

IT House January 26 news, Nvidia in 2018 RTX 20 series graphics card for the first time to use real-time ray tracing technology, and then light tracking technology has become a key technology to further the game screen effect. At present, Twitter blogger @0X22H found that Nvidia recently published a research report on light-chasing technology, which shows that they are working hard to develop ways to improve the performance of light-tracking technology.

Nvidia's report, co-published with the help of Georgia Tech's Sana Damani, gave the technology an abstract name to improve light-chasing performance: "GPU Subwarp Interleaving."

This report is highly technical, but it is generally intended to improve the performance of optical tracing by addressing the possible loss of GPU calls to warp in ray tracing operations. The so-called warp is that when the GPU performs massively parallel operations, many of the same operation inputs will be packaged into a set of parallel executions, becoming the smallest unit of execution, which is wrp.

In the report paper, Nvidia notes that this new "technology" has improved real-time ray tracing efficiency by an average of 6.8 percent and best-case results by 20 percent. However, the report goes on to point out that the technology requires changes to the architectural level of GPU hardware to be implemented. This means that future gamers will not be able to reap such benefits with Nvidia-driven upgrades.
