# What do users report when they time HY-WorldPlay, Hunyuan-GameCraft and Matrix-Game-2 themselves (including the offloading, compile and consumer-GPU cases), and how do those logs compare with the maintainers' answers?

User logs show large, flag-dependent gaps. HY-WorldPlay AR-distilled (480p, 125 frames, 4 GPUs): 3-4 minutes reported on 4xH800 and 4xH20 versus about 35 s measured by a maintainer on 4xH20; a user says turning offloading off gives about 35 s (about 3.57 frames/s), and removing repeated transformer CPU-GPU moves cut chunk 1 from 33.59 s to 5.89 s in another report (maintainers merged changes). The Wan2.2-5B variant on 4xA100 shows 90-368 s for the first four chunks and about 3.4 s per chunk afterwards (about 4.71 frames/s if a chunk is 16 frames); a maintainer blames torch.compile start-up. Maintainers say the code is not real time on an RTX 4090. Hunyuan-GameCraft users report about 12 minutes for one action on a 4090 (low-VRAM script) and 40 minutes for under 60 s of video on 8xH20; a maintainer says 8xH20 takes 2-3 times longer than their 8xH800 setting. Matrix-Game-2 users report about a minute of stall before the first response; no user FPS figures were found.

Curator qualifications: User logs show large flag-dependent gaps (offloading, repeated CPU-GPU moves) for HY-WorldPlay: minutes vs ~35 s on similar hardware.
