v1.2.0 - Apple Silicon GPU Support

[Enemyx-net]

🎉 Apple Silicon Support

• MPS Backend: Added GPU acceleration for Mac with Apple Silicon (M1/M2/M3)
• Automatic Detection: Seamlessly detects and utilizes MPS when available
• Performance Boost: Significant speed improvements over CPU-only processing

🍎 What's New

Metal Performance Shaders (MPS)

• Native GPU Acceleration: Leverages Apple's Metal framework for neural processing
• Automatic Backend Selection: No manual configuration needed
• Full Compatibility: All VibeVoice features work with MPS acceleration
• Fallback Support: Gracefully falls back to CPU if MPS is unavailable

⚡ Performance Improvements

On Apple Silicon Macs:

• ✅ 5-10x faster generation compared to CPU-only mode
• ✅ Lower memory pressure with efficient GPU memory management
• ✅ Better power efficiency using dedicated neural engines
• ✅ Smoother workflows with reduced generation times

🖥️ Supported Devices

• M1: MacBook Air, MacBook Pro, Mac mini, iMac
• M1 Pro/Max/Ultra: MacBook Pro, Mac Studio
• M2: MacBook Air, MacBook Pro, Mac mini
• M2 Pro/Max/Ultra: MacBook Pro, Mac Studio
• M3: MacBook Pro, iMac
• M3 Pro/Max: MacBook Pro

💾 Installation

Install via ComfyUI Manager or manually:

git clone https://github.com/Enemyx-net/VibeVoice-ComfyUI

📋 Notes

MPS support is automatically enabled on compatible devices
No additional configuration or dependencies required
Intel Macs continue to use CPU processing as before
Windows/Linux users are unaffected by this update

🔧 Technical Details

The implementation uses PyTorch's MPS backend, providing native Metal acceleration while maintaining full compatibility with existing workflows and features.
