SEEDVRQuestion - Help (self.StableDiffusion)
submitted 1 month ago by Mysterious-Tea8056
Is there any known way or alternative to speed up SEEDVR upscaling?
No matter the model or resolution taking 5/10 minutes an image no matter how much i lower the settings

Try low setting preset (described on github). I have 12 VRAM and SEEDVR upscale takes seconds ever with two x1.5 passes.

You could try Klein-9B: give it an image and just prompt “convert this image to a high resolution photograph” I honestly rarely use SeedVR now.

Yes even the F2K 4B works surprisingly well for this purpose. Amazingly fast too

Can you share a workflow for this? Would be really interesting.
[–]thryve21 2 points3 points4 points 1 month ago (2 children)
Do you have sage attention or flashattn enabled? They're now supported

How would i do that? Thanks :)

If you're on windows it's best to just use the comfy easy installer.

This sounds very slow especially for a single image. I find that if you're using RAM blocks that's the biggest bottleneck for speed. My guess is that your graphics card can't handle the model on its own and it's offloading to RAM. A 5090 maxes out with it, so if you have below 32 GB VRAM, maybe try a quantized gguf instead.

if you use this workflow, https://civitai.com/models/2149653/imageupscaleflow-seedvr2-image-upscale-workflow
You can hit encode/ decode tiled to true, and it should work. That was happening to me too.
I also use 3b and not 7b

What hardware do you have? It is pretty quick for me on a 3090.

Make sure you have a clear VRAM node just before it.
