Shadows of Cold War: A Scalable Approach to Shadowing

Kevin Myers

Call of Duty Black Ops Cold War launched across several generations of hardware. To deliver the best experience for players on original Xbox/PS4 to Next-Gen consoles and PC, we developed a system to automatically scale shadow quality. The system allows for true ray-traced shadows at the high-end, falling back to a dynamic-res shadowmap system that supports plausible contact hardening. This dynamic-res system works within a fixed memory budget and perf-target, delivering shadow resolution where it is needed across an unrestricted number of lights.
