Zero Racers 0.1.1 reduces color, memory-access and rewind overhead while preserving existing gameplay and the optional experimental multiplayer features.
The matched 4,000-frame color route used 23.6% less CPU and delivered 30.0% higher uncapped throughput on the i5-4670 test host. All three pairs improved; reference A/A variation was 0.11%. Stereo, audio synthesis and normal 32-entry/six-frame rewind were retained. Physical GPU performance was not measured.
16/16 Ctests pass. The release's execution sections match the owner-cleared review build; the version bump changes only its strict snapshot identity string. Prior 39 paired route checkpoints, both-eye/PCM comparisons, current/fresh-process save/load, rewind, four-player native/interpreter and two-peer LAN state/rematch evidence is retained. This is not a new Internet traversal or physical-controller qualification.
Color 0.2.1 and experimental Multiplayer 0.1.0 remain opt-in. Keep native saves, settings and mods when updating. Execution snapshots are build-specific. See qualification.json and SHA256SUMS.txt.
