ComfyUI update causes OOM errors for Stable Diffusion users

By PulseAugur Editorial · [1 sources] ·

A user on Reddit reported issues with ComfyUI version 2.2 after an update, experiencing Out Of Memory (OOM) errors that prevent workflows from completing. The user noted that previously functional workflows, which rendered in 64 seconds on an NVIDIA RTX 5090 with VRAM usage below 26.5 GB, now crash or take significantly longer. After trying various command-line flags, the user found that using `--reserve-vram 4.0 --disable-smart-memory` resolved the OOM errors and even slightly improved render times. AI

IMPACT Potential disruption for users of ComfyUI, a popular tool for Stable Diffusion workflows, due to software update issues.
