🎮 Game Installation Guide

Diablo IV Setup (Complete Automation)

# 1. Linux host preparation
./all-scripts/get-diablo4-working.sh

# 2. Windows VM scripts (run in VM)
# Copy to Windows VM and run as Administrator:
.\complete-diablo4-setup.ps1      # Base setup
.\opengl-force-mode.ps1           # GPU fix
.\diablo4-opengl-launcher.ps1     # Create launcher

# 3. Launch game
# Use desktop shortcut "Diablo IV OpenGL"

🔍 Troubleshooting

Common Issues & Solutions

❌ GPU Error 43

# Solution: Use OpenGL renderer
./all-scripts/fix-diablo4-gpu-detection.sh
# Run in Windows VM: .\opengl-force-mode.ps1

❌ VM Won't Start

# Check VFIO binding
./all-scripts/check-vfio-setup.sh

# Verify system configuration
./all-scripts/vm-setup-checker.sh

❌ Poor Performance

# Optimize VM settings
./all-scripts/virt-optimize.sh

# Check CPU governor
echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

❌ No Display Output

# Setup Looking Glass
sudo pacman -S looking-glass
# Ensure SPICE display is configured in VM
