Recomendations:
Use the "DPM++ SDE Karras" or "DPM++ 2M Karras" sampler with only 20 steps for better quality. "DPM++ SDE Karras" has better quality but is twice as slow.
Use the CFG scale between 5 and 9. CFG scale at 7 is recommended.
Resolution between 512 and 768 using "Hires. Fix" or other form of upscaling.
Tips for a better prompt:
Use (word) for larger weight and [word] for smaller weight and word:0.5 to set the weight manually.
Recomendations for improvement on performance:
Use Token merging ratio 0.5 on optimization settings.
If you have a GPU with low VRAM, use --medvram on command line arguments (webui-user.bat on Windows).
Changes on version 2:
Version 2 has an image quality more similar to recent professional cameras and has fewer visual glitches in image generation. If you noticed any aspect that got worse in version 2. Leave your observation here.
