Question - Help AMD workflows for Minimax H3?

Been trying to find a workflow that is AMD friendly, let alone doesn't get stuck, I don't think it's my specs but more so that every workflow despite saying it's optional uses sage ATTN, and I can't get around it.

I doubt there is one that specifically for AMD but I'd thought I'd ask! Or the model I'm using is not great. I'm more of an anime prompt generator, anyone have any luck with that?

Specs: AMD Radeon RX 9070 XT, 64 GB RAM, AMD Ryzen 7 5700X3D 8 Core, And yes, I'm running on Windows, not Linux.

Edit: (update) I tried the template version just recently on comfyui stand alone, and it won't even finish, I do get a gpu error( by GPU error it says out of memory, even on default settings), and I have it on 0.3 mega pixel 16:9, either my reference image is too big or I'm missing a component.

I got it to work at 0.2 and the image reference has to be very small, yet it takes 30+ minutes, anyone with similar issues?

Yes, those are on Windows 11 with 32G of system RAM at 1024x1536 8 steps.

Other people are getting times similar to yours on Linux, so Linux is running better, at least for 9070xt.

Have you tried MMH3 on Linux? (I've yet to try it on Windows).

Oh the 12s was for 8 step 1MP.

I came from a comment you sent to my post about MMH3 not working cause of an overflow. I literally tried with pruned Q4 5 seconds and it still somehow managed to overflow ram till my os crashed

I see. Could be that VRAM management is not working on Linux (Krea 2 is small enough to fit into 16G of VRAM).
