# Loading command...Frequently Asked Questions
How much VRAM does ComfyUI_LucidFlux require?
ComfyUI_LucidFlux requires a minimum of 12288MB (12.0GB) of VRAM for base operation. For optimal performance, a GPU with at least 24GB of VRAM is recommended. Low VRAM mode is not supported for this node.
Can I run ComfyUI_LucidFlux on an RTX 3060, RTX 4070, or RTX 4090?
❌ RTX 3060 (12GB): Insufficient VRAM (needs 12.0GB minimum). ❌ RTX 4070 (12GB): Insufficient VRAM (needs 12.0GB minimum). ⚠️ RTX 4070 Ti (16GB): Can run, but may experience performance issues or require low VRAM mode. ✅ RTX 4090 (24GB): Yes, fully compatible with 9.6GB headroom
How much VRAM does ComfyUI_LucidFlux take on an RTX 3060 vs RTX 4090?
On an RTX 3060 (12GB VRAM), ComfyUI_LucidFlux will struggle or run out of memory on an RTX 3060 (12GB) without aggressive memory offloading (using --lowvram), as the node's base footprint of 12.0GB takes up a large portion of the card's capacity. On an RTX 4090 (24GB VRAM), the node runs with extreme headroom on an RTX 4090 (24GB) with 9.6GB of dedicated headroom. This allows you to combine the node with massive models (like FLUX.1 Dev, Schnell, or Hunyuan Video) in full precision (FP16) without any offload flags.
What PyTorch version does ComfyUI_LucidFlux need?
ComfyUI_LucidFlux requires the following PyTorch-related packages: torch, torchaudio, torchvision. Ensure your ComfyUI environment has these installed. Ensure your PyTorch installation matches your CUDA version (use torch.version.cuda to check).
What Python packages are required for ComfyUI_LucidFlux?
To run ComfyUI_LucidFlux, you need to install: accelerate, attr, attrs, boto3>=1.34, botocore>=1.34, einops, fvcore, hydra-core==1.3.2, imageio, iopath, loguru, numpy, pandas, pynvml, termcolor, torch, torchaudio, torchvision, tqdm, transformers, wandb. You can install these using pip or add them to your requirements.txt file.
