ComfyUI-NodeSnapshots plugin uses bitmap caching to 2-3x frontend FPS on large workflows

External_Quarter · reddit · 2026-09-19

A new open-source ComfyUI extension, NodeSnapshots, tackles frontend lag on large graphs: since nodes and links are mostly static, the plugin replaces their expensive rendering with bitmap placeholders, redrawing only on direct interaction. On a 350-node workflow, a congested section went from 20 FPS to 60 FPS. An earlier whole-graph screenshot approach was faster but caused noticeable pauses; NodeSnapshots instead captures individual nodes in small idle batches and reuses each image independently. It supports both Legacy and Nodes 2.0 frontends (Legacy benefits more), requires no inference nodes, Python dependencies, or workflow format changes.
