**Foundry Virtual Tabletop (VTT)** is a subscription-free virtual tabletop for playing tabletop role-playing games like Dungeons & Dragons, Pathfinder, Call of Cthulhu, and more. Hosted directly on **The Nest**, Foundry provides interactive maps, dynamic lighting, integrated character sheets, soundscapes, and real-time multiplayer collaboration.
> Foundry VTT runs as a single service on The Nest, which means **only one World (campaign) can be actively hosted at any given time**.
>
> * **Admin Password:** Switching active campaign Worlds or installing new Game Systems and Modules requires the server's admin password.
> * **Requesting GM Access:** Reach out to an administrator on Matrix to get the administrative password and receive a quick setup overview.
> * **Session Scheduling:** Be sure to schedule game times with other GMs on Matrix to avoid schedule overlaps or accidental world switching during live sessions!
* **Hardware Acceleration:** Foundry uses WebGL to render dynamic lighting, fog of war, and canvas effects. Ensure **Hardware Acceleration** is turned **ON** in your browser settings (`chrome://settings` or Firefox settings) for smooth performance.
* **Recommended Devices:** While mobile devices can technically access the web interface, a desktop, laptop, or tablet with a dedicated mouse/trackpad is strongly recommended for managing map vision and token navigation.
* **Performance Tuning:** If you experience lagging or high fan noise, lower the **Maximum Frame Rate** or disable soft shadows under **Settings → Configure Settings → Core Settings**.
* **Audio & Video Setup:** Foundry includes native browser WebRTC for audio and video calls. Be sure to grant camera and microphone permissions when prompted by your browser.
