Here comes the FLUX one!

Samplers

• Black Magic: [Forge] samplers (slow but very good.)

• The Fastest: Euler (yet blurry).

• Nearly the same: DPM++ 2M (the sharpest), HEUN (a bit more detailed than DPM++ 2M, but a bit more blurry), DEIS (the middle ground between DPM++ 2M and HEUN), HeunPP2 (better than DPM2, slightly different than the rest.)

• The rest: the rest of the samplers are glitchy or don't work at 20 steps well.

Schedulers

Best combos:

• Euler + Simple.

• DEIS + BETA.

• DEIS + KL Optimal or SMG Uniform.

• [Forge] samplers + KL Optimal, SMG Uniform, or Simple (but results are better with the other two.)

What else?

• Euler VS DEIS: DEIS gives a more sharp and contrasting image.

• The BETA scheduler works well only with DEIS, the rest are so-so in comparison.

• [Forge] samplers output very epic results with KL Optimal and SMG Uniform schedulers and low Distilled CFG: 2.2.

• KL Optimal loves to tint results in too warm or cold tones.
