echo "🎯 Emulator launched with ANGLE rendering!"
echo ""
echo "📋 Configuration:"
echo "  - ANGLE indirect rendering"
echo "  - NVIDIA GPU offloading"
echo "  - 6 CPU cores allocated"
echo "  - 4GB RAM allocated"
echo "  - Hardware acceleration enabled"
echo "  - Fast startup (no boot animation)"
echo "  - Clean state (no snapshot loading)"
echo "  - Bluetooth disabled (prevents hangs)"
echo ""
echo "🔍 Benefits:"
echo "  - Better NVIDIA compatibility on Linux"
echo "  - Avoids mixed Vulkan+OpenGL binding issues"
echo "  - More stable rendering pipeline"
echo "  - Good fallback when host GPU mode fails"
