Easel Develops Custom Physics Engine with Incremental Rollback for Larger Multiplayer Games

Summary

Easel has developed a custom-built physics engine with incremental rollback capabilities, replacing the off-the-shelf engine that required snapshotting and rolling back the entire world every frame. This new architecture allows games built on Easel to support larger, more complex multiplayer environments (like Among Us-scale games) without the performance overhead that previously limited world size. The incremental rollback approach only processes changed elements rather than the entire physics state, making it feasible to run predictive multiplayer at scale.
