Temporally Dense Ray Tracing by Pontus Andersson, Jim Nilsson, Marco Salvi, Josef Spjut, and Tomas Akenine-Möller.
Hang on, measuring monitor refresh rate...
Explanation: the goal here is to see how close to vanilla 240 FPS rendering our method comes.
Left: 60 FPS vanilla rendering.
Middle and right: 240 FPS rendering with our method (middle) versus vanilla (right).
Note: at 240 FPS, our method (middle) is rather close to 240 FPS vanilla (right), while only tracing 25% of the rays.
Make sure to click the 240 FPS radio button for best results.
