🎮 DeckStream v1.0.0 - Handheld Gaming Runtime

DeckStream is an open-source, on-demand virtual filesystem gaming runtime for the Steam Deck and handheld Linux PCs (SteamOS 3.5+).

Instead of filling limited local handheld storage with 100+ GB installations, DeckStream mounts your personal remote game libraries (WebDAV, Nextcloud, TrueNAS, Unraid, or S3/MinIO) over an unprivileged Copy-on-Write FUSE layer, launching titles natively through Proton while streaming only the file blocks the game reads during gameplay.

✨ Highlights & Key Capabilities

  • ⚡ FUSE On-Demand Streaming: Play large PC titles directly from personal remote storage with chunk-level VFS caching.
  • 🛡️ Copy-on-Write Sandbox (fuse-overlayfs): Remote storage stays 100% read-only. Game writes, INI tweaks, and DirectX/Vulkan shader caches land in an isolated upper layer on local MicroSD or NVMe storage.
  • 🎮 Handheld Decky Loader Integration: Native SteamOS Gaming Mode QAM plugin to monitor throughput, check cache consumption, clear cache, and toggle per-game battery modes.
  • 🔋 Per-Game Deck Mode: One-tap toggle in the Decky panel capping framerate at 30 FPS and setting low graphics presets for up to 130% longer battery life.
  • ⚡ Range-Request Hedging: Built-in hedge proxy monitors range requests and automatically races duplicate connections if a remote chunk stalls past 200 ms.
  • 🌙 Overnight Startup Warmup: Pre-fetches startup profiles for recently played titles while on the charger dock.
  • 💾 Automated Save Snapshots: Post-session save backups via Ludusavi preserve progress across Proton prefix updates.
  • 🛠️ Self-Healing Doctor: Built-in doctor.py diagnostic tool checks Wi-Fi power-saving toggles, DNS latency, VFS responsiveness, and systemd service health.

🚀 Quick Installation on Steam Deck

Switch to Desktop Mode, open Konsole, and run:
