ComfyUI Video Upscaler Adds W4A8 Quantization Support

By PulseAugur Editorial · [1 sources] ·

A new version of the ComfyUI-SeedVR2-VideoUpscaler-with-TensorRT tool, v1.6.6, has been released, introducing support for W4A8 quantization. This update aims to improve image quality over NVFP4 while maintaining similar file sizes, though VRAM consumption is comparable to ConvRot INT8. The release also notes that DisTorch2, previously implemented to manage VRAM spikes, caused excessive usage and is therefore not recommended for use with this version. AI

IMPACT This update offers improved image quality and potentially more efficient VRAM usage for video upscaling tasks within the Stable Diffusion ecosystem.
