Latest NVIDIA drivers installed (Oct 19th 2023) slows down ComfyUI

[Marventus]

Installed the latest NVIDIA drivers and the KSampler is now taking 4-5 times more time to do the same amount of work that happened before.

I'm not seeing this. I installed the drivers that dropped about two days ago and I still see the same performance on my production workflow.

I cannot tell what has happened exactly. It now works fine as long as I am only generating a few images. If I do a stack of 15 or more it suddenly slows to a crawl and then crashes. 1024x1024 size images. I will give it a few more tests over a few days, this was with SDXL only. 1.5 is working fine.

I'm not using sdxl

noticed that as well since last nvidia update, on sdxl as well, KSampler and vae decode are becoming 1.5-2x slower than usual

Yeah its definitely happening, I ran out of VRAM today - that has never happened before.

Same issue. Using the same workflow I've been building for the last week or so. Updated yesterday, managed to get a couple of exports out and since then I just keep hitting CUDA out of memory errors. A couple of models will still output a result, but models that were working previously bring up OOM errors, etc, etc.

One thing I did notice after playing with my page file and keeping an eye on my resources was that my RAM was filling up alongside my VRAM and then spiking before comfy errored out.

New to this so not sure if any of this is related, or if it means I just need more RAM.

At the moment I'm on running an RTX 3080 with 32gb DDR4 running 512 x 512 and 512 x 768 generations.
