The game launched in 2015 with delay-based netcode, which was widely criticized for high input lag and instability.
MKX became a landmark case for successfully implementing GGPO-style rollback in a high-fidelity 3D fighting game. This improved the online experience to the point that matches with up to 150–200ms ping could feel nearly indistinguishable from offline play. Mortal Kombat X РїРѕ сети
Retrofitting rollback into an existing engine required a complete overhaul of the game's simulation and state management. The "8 Frames in 16ms" title refers to the technical feat of having the CPU re-simulate up to 8 frames of gameplay within a single 16.6ms window to ensure synchronization without visual lag. The game launched in 2015 with delay-based netcode,
The paper details the drastic engine changes and custom tools needed to make "snapshotting" game states efficient enough to avoid dropping frames during the rollback process. Why It Matters Retrofitting rollback into an existing engine required a
This report describes the massive engineering effort to retroactively replace MKX's original "delay-based" netcode with a high-performance system.
