I just did a batch generation using settings:

With hires upscale by 2 times, and it took ~48 minutes. I must get myself into tweaking settings a bit to make the most of my gpu without running out of vram..
Oh, and here are some of the pics from the batch:

Hmm.. I do 512x1024 upscale 1.5x, with a few LoRa, takes 48s.. I thought it was slow

It all depends on what sampler you use, how many steps, etc.
When i try to generate 512x1024 with 1.5x upscale gpu goes brrrrr and vram error pops up XD

 

[fanciful_dream]

How much VRAM? I want to do even higher resolution so I need to get a 4090 lol

At the moment i'm sporting rtx 2060 with 6GB vram. Shit hits really hard on the gpu

You will need to sell a kidney to afford a 4090 card.. You can probably get away with a 3060 or 3070 12Gb for much less money.

Higher resolution on it's own doesn't do much for quality. Hires steps is what makes the big difference for details and image quality.
If the hires steps is set to 0, it does the same amount as the sampling steps I believe. It's a good idea to set the hires steps to 20-30, or to 2x the sampling steps if you wish to keep the composition and with a low denoising strength like less than 0.3

Does the number of hires steps make a huge difference in vram usage? Right now i had 70 sampling steps and 70 hires steps, as it was set to 0. And i can't upscale the 512x512 image more than by 2, even 2.05 crashes.

Have 3080, want upgrade lol!

I have not done any tests but probably. 70 steps is overkill for both sample and hires. You get more out of it with 20-30 sample steps and 40-60 hires steps imo. Try out 20 sample steps with 40 hires and see how high you can set the multiplier.
Then you can play a bit with denoising. Set it low if you wish to retain the composition 0.3
Also don't forget to use the cuda memory "fix". It gives a small boost.
Add "set PYTORCH_CUDA_ALLOC_CONF=garbage_collection_threshold:0.6,max_split_size_mb:64" to webui-user.bat
I have not done any test with different threshold settings, 64mb seems to work well for me, this is probably dependent on your Vram.

*I forgot to say that the image ration makes a big difference for vram. A wide image means more pixels and more vram, so go with either portrait (narrow with x height) or landscape (wide with x low height).
I use 512x768 and my multiplier can go to 2.5 but is more comfortable at 2.4 .
You can use this ratio (1.5) but stay under 512, meaning w<512. Example 384x576 or 400x600 or 424x636 etc.

If you have 12Gb vram, it's plenty. What is your max hires multiplier? And max end resolution?

 

[Mr-Fox]

A couple more beach chonks.



Yeah I know, the hands.. But no one is going to look at the hands..

I have 10GB. End up maybe 900x1500 images. Hires 30.

You didn't understand me correct. I meant how high can you set the Hires multiplier ("upscale by") and what will the end resolution be? If you use 512x768 like me and the maximum multiplier 2.5 the end resolution will be 1280x1920.
My question is: how much will your 10GB Vram give you ? what is your max settings?
I have an old pascal card, RTX 1070 8GB.

I can do about 1140x1900, from 600x1000 upscale by 1.9

You should be able to do more. I have 8GB Vram and I can get 1280x1920 as my max. 2GB more vram should get you well over 2k in resolution.

 

[fanciful_dream]

Oh, I can't though
