Summary
This post details the technical implementation of Roblox Reality, a hybrid architecture for photorealistic, multiplayer gaming. It describes the integration of the distributed Game Engine with edge-based Video World Models. Key technical components include: server-side state management for consistency, speculative client-side simulation for low latency, cloud-based LOD and compositing systems for asset delivery via CDN, and edge-based Video World Models (Super Upsamplers) powered by cloud-edge GPU infrastructure for visual realism. The post also touches on the rendering pipeline, including the client rendering the video feed and potentially overlaying locally rendered avatars for low latency.
