Description

Variable rate ray tracing in call of duty: modern warfare 4 is Michał Olejnik's SIGGRAPH 2026 Advances slides on stabilizing denoised ray tracing in Call of Duty multiplayer.

Variable Rate Ray Tracing reallocates per-pixel rays using temporal gradients, disocclusion detection, and a GPU scheduler with constant total rays per frame.

Rendering engineers shipping RT in fast shooters should know denoising and motion vectors.
