NVIDIA RTX Direct Illumination Enables Games with Up to Millions of Dynamic Lights

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.
