Are you finding dpm++ 3M SDE better than dpm++ 2M SDE in sdxl?

Afaik the second order (2M) version is the recommended one to use for guided sampling vs the 3rd order one.

From here: https://huggingface.co/docs/diffusers/v0.23.1/en/api/schedul...

> It is recommended to set solver_order to 2 for guide sampling, and solver_order=3 for unconditional sampling.




It might be placebo, but I find 3M better for upscaling, when I usually set CFG quite low and use a generic prompt that doesn't describe any localised element of the picture.

Which is what it's meant for, I suppose.


In my tests it's basically been 50/50, i probably did ~40 or so comparisons when i was testing samplers and i felt like there were a couple that seemed really good on the 3rd order one, but idfk, it was very very close, I don't know if I saw a single gen where one of the two was bad but the other wasn't.
