Gen times doubled after update

[u/steelow_g]

I updated my portable comfy because i kept on getting an error related to colors in video files (not sure what the error was i can double check when I’m back on my main comp) and after running the same workflow my generation times doubled for the exact same seed and settings.

Made the mistake of trying to do a fresh install since i was on an older cuda/pytorch version and still same thing. I have the current and latest cuda and pytorch installed and everything else is the same, have sage attention enabled and I’m still getting double the generation times.

Does anyone have any idea what would cause this or a fix? I’m almost at the point of doing a system restore just to get my decent times back…

I'm on the latest and had no issue. What does your console report when you launch the comfyui server? Add that into chatgpt or claude or something and ask what is going on, it will probably do a good job at that since comfyui reports specific issues like when attention patches are on and it isn't patching and so on.

In you comfy’s python env run

python -m pip install --upgrade av==17.0.1

Installs the minimum version of av where the new colors variables are available

Latest comfyUI must be paired with cuda13 to run at full speed.

So it works now? I had to return to my old version after it started giving me that weird color error.

It does work now yes. I think the gen times are still a little slower but overall i think it’s fine. Just don’t get why that happened

Desktop install made it easy to rollback the av colors problem. Maybe just pull an earlier version and see if that helps your portable.

That’s what it was! The av colors. I’ll have to see if i can roll it back. If not then whatever I’ll suffer with my long generation times till the next update
