These are the only scheduler/sampler combinations worth the time with Flux-dev-fp8. I’m sure the other checkpoints will get similar results, but that is up to someone else to spend their time on 😎

I have removed the samplers/scheduler combinations so they don’t take up valueable space in the table.

🟢=Good 🟡= Almost good 🔴= Really bad!

Here I have compared all sampler/scheduler combinations by speed for flux-dev-fp8 and it’s apparent that scheduler doesn’t change much, but sampler do. The fastest ones are DPM++ 2M and Euler and the slowest one is HeunPP2

Percentual speed differences between sampler/scheduler combinations

From the following analysis it’s clear that the scheduler Beta consistently delivers the best images of the samplers. The runner-up will be the Normal scheduler!

  • SGM Uniform: This sampler consistently produced clear, well-lit images with balanced sharpness. However, the overall mood and cinematic quality were often lacking compared to other samplers. It’s great for crispness and technical accuracy but doesn’t add much dramatic flair.
  • Simple: The Simple sampler performed adequately but didn’t excel in either sharpness or atmosphere. The images had good balance, but the results were often less vibrant or dynamic. It’s a solid, consistent performer without any extremes in quality or mood.
  • Normal: The Normal sampler frequently produced vibrant, sharp images with good lighting and atmosphere. It was one of the stronger performers, especially in creating dynamic lighting, particularly in portraits and scenes involving cars. It’s a solid choice for a balance of mood and clarity.
  • DDIM: DDIM was strong in atmospheric and cinematic results, but it often came at the cost of sharpness. The mood it created, especially in scenes with fog or dramatic lighting, was a strong point. However, if you prioritize sharpness and fine detail, DDIM occasionally fell short.
  • Beta: Beta consistently delivered the best overall results. The lighting was dynamic, the mood was cinematic, and the details remained sharp. Whether it was the portrait, the orange, the fisherman, or the SUV scenes, Beta created images that were both technically strong and atmospherically rich. It’s clearly the top performer across the board.

When it comes to which sampler is the best it’s not as easy. Mostly because it’s in the eye of the beholder. I believe this should be guidance enough to know what to try. If not you can go through the tiled images yourself and be the judge 😉

PS. I don’t get reddit… I uploaded all the tiled images and it looked like it worked, but when posting, they are gone. Sorry 🤔😥
