Key Features of the RTX Node

NVIDIA has rolled out the RTX Video Super Resolution node, enhancing video generation on RTX GPUs. This feature is accessible through ComfyUI, either via Manage Extensions or by downloading from the GitHub repository. Included in the release are model variants such as FLUX.2 Klein 4B and 9B, now equipped with NVFP4 and FP8 configurations.

User Feedback Highlights

The communityโ€™s response is a mixed bag:

  • One user highlighted, "RTX 2060 is supported?", indicating demand for broader compatibility.

  • Another raised the question of sample outputs, asking, "No examples or comparisons? Is it better than SeedVR2?"

  • A positive note came from a tester who noted speed and clarity, stating, "I've replaced my 'Upscale 2x LANCZOS' nodes because itโ€™s fast and sharp."

Performance Claims and Concerns

  • However, others claim to see little difference in quality, with one commenting, "The image quality remained unchanged; details were still blurry."
