ComfyUI Dual GPU Test: Raylight Multi-GPU Setup Pitfalls and Performance Regression
Specialist_Pea_4711 · reddit · 2026-08-12
A user shares their experience setting up a dual-GPU configuration (two 5060TI 16GB) in ComfyUI. Lacking workflow expertise, the author used Claude to help configure the Raylight nodes.
Test Results:
- Performance regression: The speed using dual cards is actually worse than a single GPU.
- Compatibility limits: Raylight nodes currently do not support key nodes like Spectrum or Sol attention, limiting optimizations.
The author questions the actual benefit of dual GPUs in ComfyUI and is considering selling one card. They have shared the Claude-generated workflow configuration for community troubleshooting.
