Nvidia research promises 2x to 3x faster path tracing with better visuals

Nvidia detailed an updated ReSTIR path tracing method that cuts noise and divergence while unifying direct and indirect lighting calculations.

In tests, it rendered scenes about 2x to 3x faster, pointing to a major reduction in the GPU cost of path tracing.

The company also highlighted Shader Execution Reordering, Opacity Micromaps, and RTX Mega Geometry as part of its broader graphics push.

The research aims to make ray-traced games more practical without sacrificing realistic lighting and reflections.
