Happy to announce that I’ll be presenting my work on Variable Rate Ray Tracing in Call of Duty: Modern Warfare 4 as part of Advances in Real-Time Rendering at SIGGRAPH 2026.
Ever since ray-tracing hardware debuted, I’ve been obsessed with trying to fix common screen-space denoising artifacts to make ray tracing viable for competitive multiplayer gameplay.
VRRT is my solution: through smart on-screen ray reallocation and load balancing, we achieve a fixed frame time with no disocclusion or lag-on-movement issues. See the course page for the full abstract.
