RECOMENDED PARAMETERS FOR BEST RESULTS:

◦ Sampler: DPM++ 2M SDE / DPM++ 3M SDE / DPM++ SDE

◦ 30-40 Steps.

◦ CFG: 3-6 (low for more realism, high for more stylization)

◦ The model was on trained mostly on 1024x1024, 832x1216, 1216x832, 896x1152, 1152x896 resolutions, so it could help the quality if you used these (although that's not necessary - it behaves nicely on other aspect ratios as well).

◦ Highres fix: Upscale by 1.35-1.5, denoising strength ~0.4, upscaler - 4x NMKD Superscale or Siax.

For the distant shots of people you probably wanna use highres fix/upscaling and/or adetailer.
