Sudden extreme performance loss

[ugsusu]

Hi everyone!

I've been playing with SD since February and have been getting some great results. It's a fun tool and helps me a lot with my workflows. However: I've noticed an extreme loss in performance lately.

I used to get about 3-4 it/s when generating images, now it looks more like 4-5s/it. My GPU is an RTX 3070 and I'm currently on the release candidate branch (just to see if increased the speed at all).

What I tried to get the speed back:

• Use pytorch 2.0 -> No effect
• Replaced the cudnn dll files inside the pytorch folder ( https://developer.download.nvidia.com/compute/redist/cudnn/v8.7.0/local_installers/11.8/ )
• Use xformers -> No effect
• Various command line shenanigangs like --opt-sdp-no-mem-attention or --opt-sdp-attention
• Update my GPU drivers, currently 537.13
• Set Cross attention optimization to Doggettx

Is there anything I'm missing?

Also please excuse me. I have no idea about development at all. Before using SD I didn't even know what a git is let alone how to pip install things. Maybe I'm asking questions wrong or am missing things.

EDIT: Downgraded to 531.68 as suggested in #11062 and the issue seems to be resolved - apologies for opening this should've been more thorough in my search!

Ah I was hoping that would've been fixed by now since that issue is from June....

well if I receive reports of it being fixed I will unpin it.......

Yeah I downgraded to 531.68 and speeds are back to normal. Apologies for opening this and thanks for your reply.

Did anyone try 545.31? I can just tell I'm not having any issues with it.
