From the sources read (synthesis): (a) free-running action-conditioned generation with released weights is documented at 25 FPS on an H100 (Matrix-Game 2.0, 352x640), far slower for higher resolution or larger models (GameCraft 0.25 FPS, 6.6 distilled, 720p); (b) the only documented consumer-GPU real-time path, Matrix-Game 4.0, does not free-run: a game engine keeps state and supplies low-poly frames which the model renders, 480p, with three trained scenes (two shooters, one racing); (c) memory needs range from about 9-13 GB (MG4 on RTX 5070 Ti/5080) to 24 GB minimum (MG2 README, GameCraft README) and 108-123 GB for a compared system. For previs, the setup question is therefore which trained scene or domain applies, not only the GPU. First safe steps are to record each figure's setting, run only code and weights after a licence and checkpoint-format review, and measure key-press-to-frame latency on the target hardware.

Curator qualifications: The synthesis (only free-running consumer real time is engine-assisted MG4; others are H100-class) follows from the sources. Previs/game-prototyping use is a proposal.

Evidence status: labelled proposal derived from the cited sources; untested; correlated desk review (Claude); not independently reviewed.

Evidence claims:
- [proposal] From the sources read (synthesis): (a) free-running action-conditioned generation with released weights is documented at 25 FPS on an H100 (Matrix-Game 2.0, 352x640), far slower for higher resolution or larger models (GameCraft 0.25 FPS, 6.6 distilled, 720p); (b) the only documented consumer-GPU real-time path, Matrix-Game 4.0, does not free-run: a game engine keeps state and supplies low-poly frames which the model renders, 480p, with three trained scenes (two shooters, one racing); (c) memory needs range from about 9-13 GB (MG4 on RTX 5070 Ti/5080) to 24 GB minimum (MG2 README, GameCraft README) and 108-123 GB for a compared system. For previs, the setup question is therefore which trained scene or domain applies, not only the GPU. First safe steps are to record each figure's setting, run only code and weights after a licence and checkpoint-format review, and measure key-press-to-frame latency on the target hardware. · locator: Table 3 · source: https://github.com/SkyworkAI/Matrix-Game/blob/c7a88bfc039cd97695082484986e95b962390676/Matrix-Game-4/README.md
