Requirements#
Operating system and GPU#
- Windows 10 or Windows 11, 64-bit (the platform currently supported).
- An NVIDIA GeForce RTX GPU with a current driver. Image work is comfortable on mid-range cards. Video generation and LoRA training use int8 model packs and run on 16 GB of VRAM; 24 GB gives more headroom for long takes.
- No other application should be holding GPU memory while you generate. Voice assistants, local LLM servers and similar tools that sit on the GPU slow every step down several times over. See Troubleshooting.
System memory and disk#
| Workload | RAM | Notes |
|---|---|---|
| Image generation | 32 GB | Large image models stream through system RAM. |
| Video generation | 32 GB minimum, 64 GB recommended | Video packs are memory-mapped and pinned in RAM while a take renders. |
| Character LoRA training | 64 GB recommended | Training pins about 26 GB of host memory on top of the model pack. |
Plan on a fast SSD with at least 100 GB free for the starter models, and more if you bring your own checkpoints. Video takes and training outputs are written under your install folder; see Storage and paths.
PostgreSQL#
Maystro keeps projects, galleries and training runs in a PostgreSQL database running on the same machine. Install PostgreSQL before you run the launcher (version 15 or newer is recommended) and create a database and a user for Maystro. The launcher asks for the host, port, database name, user and password, and tests the connection before it installs anything.
Network#
Internet access is needed to activate the license, to download Maystro updates and to fetch models. After activation the app keeps working offline for extended periods; see License and activation.
