CRG vs ECS: Hardware-Bound Stress Test
Classic ECS (Swap & Pop)
0.0 ms
Memcpy tax: 0%
CRG (Structural Immunity)
0.0 ms
Routing tax: O(1) Constant
Break-Even Insight: In traditional ECS, structural changes trigger a `memcpy` of the entity data. As entity size grows, memory bus saturation becomes a bottleneck. CRG leverages structural immunity: we only move function pointers (8 bytes), making the mutation cost independent of the data size.
