You NEED this if you want to get a clean Flux upscale with great detail, along with minimal or no streaking/artifacting that can sometimes occur with Flux. Check the results and see for yourself!
Description
Made several tweaks to guidance/CFG, upscaler selection, added new methods to try to tackle rare artifacting, regrouped things more intelligently, and noted what can be disabled in the flow.

Without even trying this yet I can already vouch for it. You've been generating images for my LoRAs that look amazing which were upscaled I'm assuming with this workflow. Thank you.
Thanks so much! And you are correct, this workflow is my daily driver now :)
can i ask why two pass is 0.6denoise+0.4denoise?why not just 1 denoise？
Hi, first pass is 1 denoise since it is essentially creating the image from nothing.
Then there's a latent upscale, which gives it room to work and improve.
2nd pass is .6 denoise (I have since changed to .5 denoise to stay closer to original - you can play with this) which largely keeps original composition but adds further detail.
Final pass is .4 denoise which doesn't change composition any further but refines details nicely.
I found this combo does take a little time to run (2 mins total on a 4090) but gives GREAT results.
I often take it even a step further and run the final upscaled image through an image resizer node set to 2048 and then I run it through Florence2 to have it remaster the prompt and after that I run it back through the latent upscaling process again for even better results. It takes about 15 extra minutes on a 3090 for that to process, but it can be worth it because of how many more fine details you can pull out. It's more prone to getting that flux screen door effect though, so sometimes I have to use 1536 on the resize and it's not as bad. It also takes half the amount of time to process at 1536.
@EnragedAntelope understood,thx
very good quality. thanks. can you add a second lora for 1.1?
Thank you for the tip! And yes, I will look into doing that.
Hi again, please see updated version. Enjoy!
Thank you!
@Psk0 You're welcome! And thank you again for the buzz.
