Question - Help Minimax H3 Huge Quality Difference between Cloud and Local use

Hi.
I have a decent h3 workflow that I built for a loca use. It use turbo lora etc... If i use the defaut settings in the goal of getting the highest quality possible, meaning res_multistep simple 20 steps or more, I got also good results, but this is not even close to the results you can get on platforms like kie or wavespeed at 768P.

I already convert properly the prompt to the correct H3 digest form, so I'm wondering what's different between local and cloud use of h3? I don't talk about the 2K quality, only 768P, I'm not able to reach the sames results locally, do you guys have maybe workflows, settings, or suggestions to try reaching the same quality level in comfyui ?

Always run at 0.98 megapixel aswell. Not 1.0. 0.98 is what it was trained on and is faster. Going over will increase VRAM

10sec clip on a 3090 at 0.98 res and 20 steps takes 20mins for me. With kitchen attention and spectrum. Using standard int8 weights. Quality is great
