# Optimized flags for Grace-Blackwell unified memory architecture
# Key: DON'T use --gpu-only - it fights the unified memory fabric
# --disable-pinned-memory: reduces overhead on unified fabric
# --force-fp16 + --fp16-*: enables SageAttention optimization
# --fp32-vae: run the VAE in fp32 - fp16 VAE produces NaNs -> BLACK images on
#   many SD1.5/SDXL checkpoints. (Use --bf16-vae instead for a faster compromise.)
# --dont-upcast-attention: keeps attention in FP16 for speed
