GDC 2025 : Update on Xcloud Improvements

Latency Optimization

Direct Capture: Reduces input latency by 16-72ms depending on the game. Previously discussed at GDC in 2022, Direct Capture has since expanded to support nearly the entire game catalog.

Device-specific Optimizations: Adjustments to accommodate device-specific video decoders eliminated tens of milliseconds of latency for certain users.

WebRTC Implementation: Utilizing WebRTC has significantly reduced latency while enhancing resilience through improved packet-loss management.

Buffering Optimizations: Strategic buffering adjustments ensure smoother playback with minimal impact on overall latency.

Collaboration with Hardware Partners: Partnering closely with device manufacturers has led to further improvements, including optimizing device settings (e.g., activating Game Mode) for a low-latency gaming experience.

Datacenter Expansion: By increasing the number of Xbox Cloud Gaming server locations, we've further reduced network latency for many users.
