summary
Overview of a CDN-backed texture system called On Demand Texture streaming that downloads high-res mips only when encountered, stores them in per-console x-pac slices and a user cache (starts at 12 GB cache on gen‑8, 30 GB on gen‑9). Engineering tackles file I/O, SSD write caps and multiplayer packet bursts with aggressive rate limiting and verification; results are concrete: Vanguard cuts install size by about 50% package reduction, Modern Warfare streams ~220 petabytes total and averages 5 GB per user, and the system works in live play.
