Can you explain what the command line arguments are telling me?

[bismark211]

I have win 10 and rtx 4090

[bismark211]

I don't have these lines of code

[bismark211]

It doesn’t start for me exactly at 110 steps, for example, it works at 80.

@bismark211 yep, that's what i expected to hear. it's just a bug that's been adressed many times before https://github.com/AUTOMATIC1111/stable-diffusion-webui/pull/3917 and the PR that fixed it even mentions that specific step count. Wonder when it broke again?

now generation has stopped on dpm++2m

There was a rework done recently (only available on the dev branch currently) to implement DDIM, PLMS, and UniPC in a way more consistent across the board. https://github.com/AUTOMATIC1111/stable-diffusion-webui/commit/8285a149d8c488ae6c7a566eb85fb5e825145464
