??? This is just the example workflow from their HF model card. I'm not sure what you mean here as it doesn't come out well at all with the same settings I used with Perchance.
You probably want a GPU with 12GB of VRAM as that's enough to fit the entire fp8-scaled version. Also a PCIe 4 or 5 NVME SSD if you don't want model load times to be a problem, but that's about it. Linux is great for AI too.
I kind of like it in some ways. Much easier to set up events on, like how all those chairs are out there
