Has anyone gotten a 1070ti working well with ComfyUI?

My regular video card (9060XT 16GB) had to go back to Sapphire due to a warranty claim, so I brought my reserve card (a 1070ti) out of retirement. And yikes .... it's slow. A 1mp image in Z Image Turbo takes anywhere between 140-170 seconds to generate. I am using the portable windows version with pytorch cuda 12.6 and python 3.12. My regular setup is in Nobara Linux. I expected it to be slower and less capable but this seems way worse than I expected. I'm using tiny little quants of Zit and it's text encoder too, to fit within the 8GB limit, but no luck so far.

Does anyone have a setup like this working at some sort of reasonable speed?

I have tried this: https://www.reddit.com/r/comfyui/comments/1qjp7vs/nvidia_geforce_gtx_1070_with_cuda_capability_sm/

But it hasn't helped at all.

Do I just need to suck it up for two or three weeks?
