    workflow for all nvidia RTX series like 20,30,40,50 , Need Atleast 16gb ram

    6sec 0.4 megapixel video took 350 sec only while maintaining face consiste3ncy

    make sure that you have latest version of comfy ui with cuda 13 and sage attention installed on your system

    Thanks for posting your WF. Question. I have used 1 WF with Sage and another with the Spectrum speedup. Do you feel there is a noticable loss in quality when using these with H3 or is it neglectable? Thanks.
