NVIDIA RTX Direct Illumination Enables Games with Up to Millions of Dynamic Lights Apr 17, 2021 09:30 EDT
If you re a regular Wccftech reader, chances are you might have stumbled into our story about ReSTIR, a deep learning algorithm devised by NVIDIA engineers to render millions of dynamic lights in real time.
At the time, almost a year ago, ReSTIR (Reservoir-based Spatio-Temporal Importance Resampling) wasn t quite ready for game development purposes as its rendering cost was around 50ms for 3.4 million dynamic lights. That s way too much to be of any use for game developers, as programmers need to find their entire rendering budget into 16.6 ms if they target 60 frames per second.
