Setup guide

Wall Slayer wraps the full ComfyUI pipeline into a one-click desktop app. The onboarding wizard detects your GPU, WSL2 environment, and installed models automatically — you just need the right hardware foundation before you start.

System requirements

  • OS: Windows 11 recommended (Windows 10 supported)
  • GPU: NVIDIA RTX with 8GB+ VRAM (RTX 3060 minimum)
  • RAM: 16GB system RAM recommended
  • Storage: 40GB+ free for base model packs; 120GB+ for full library
  • WSL2: Ubuntu on WSL2 required for the video generation pipeline
  • Driver: NVIDIA 537.xx+ recommended for CUDA 12 support

First-run steps

  1. Run the Windows installer (.exe). It detects GPU, VRAM, and WSL2 automatically.
  2. Enter your Keygen.sh activation key from your receipt email. Requires internet once.
  3. Complete the onboarding GPU scan — it validates CUDA, VRAM, and model paths.
  4. Use the Model Manager to download FLUX.1-schnell and Wan 2.2 packs.
  5. Click Launch Engine. ComfyUI starts locally on a background port.
  6. Enter your first prompt and generate. Output appears in the wallpaper feed.

Model packs

Download only what you need. Each pack adds a generation mode.

  • FLUX.1-schnell — Fast 4-step image generation (~12GB)
  • Wan 2.2 (480p) — Text-to-video and image-to-video (~14GB)
  • RealESRGAN-x4plus — AI upscaling to 4K (~65MB)
  • UltraSharp — Alternative upscaler for portrait content (~65MB)
  • RIFE v4.6 — Frame interpolation for smoother live wallpapers (~50MB)

Common setup issues

  • Engine won't start: Ensure WSL2 is enabled in Windows Features and Ubuntu is installed from the Microsoft Store.
  • CUDA not detected: Update to the latest NVIDIA Game Ready Driver and reboot before launching.
  • VRAM OOM on generation: Use the 480p Wan 2.2 variant and reduce batch size to 1 in settings.
  • Activation fails offline: The first activation requires internet. Subsequent launches are offline.
  • Model download stalls: Pause and resume in the Model Manager. Files resume from where they stopped.
