AlayaRenderer-Flash lifts a generative world renderer from 0.56 FPS to 31.54 FPS

• AlayaRenderer-Flash turns a generative world renderer into a real-time system that synthesizes RGB frames from structured physics-engine state.
• Unlike text-to-video style frame generation, it preserves the scene structure and underlying dynamics while keeping the teacher model’s G-buffer and text-prompt interfaces.
• The paper says the original renderer was too slow for deployment; the new version reformulates it as a few-step autoregressive streaming model and adds lightweight distilled codecs.
• Reported performance jumps from 0.56 FPS to 31.54 FPS, enough to run a fully playable generative world at 30 FPS.
• Evaluation covers content preservation, temporal consistency, cross-window stability, prompt controllability, and runtime efficiency.
