Hey everyone, I wanted to share some of the new ComfyUI updates we’ve been working on at NVIDIA that were released today. The main one is an RTX Video Super Resolution node. This is a real-time 4K upscaler ideal for video generation on RTX GPUs. You can find it in the latest version of ComfyUI right now (Manage Extensions -> Search 'RTX' -> Install 'ComfyUI_NVIDIA_RTX_Nodes') or download from the GitHub repo. Also, in case you missed it, here are some new model variants that we've been working on that have already released: FLUX.2 Klein 4B and 9B have NVFP4 and FP8 variants available.
