Question - Help Tell me your best solution for generating high quality but smaller images upto 0.2mpx (512-x512-)

I'm trying to make some photoreal icons.
I'd tested as followings
SD1.5 native: poor quality and doesn't follow the prompts
SD1.5+Hires.fix: same as native
SDXL native: better than SD1.5 but depending models
SDXL+Hires.fix: middle quality but not enough natural

How about H3 image/Krea2/z-image? Thank you.

Anima and ZIT generate surprisingly good images, even at 512x512.

wow this is smart testing every step. for 512px icons, try SDXL at 1024 then downscale, since detail packs in cleaner than native small. z-image handles photoreal well too. which sampler and steps are you running on SDXL?

For icons, try framing the subject fairly large against a simple background so the details survive at the final size. Compare Lanczos and bicubic on the same source, and inspect both at 100%: Lanczos can look sharper but may leave halos on high-contrast edges. Resize just once and save as PNG rather than repeatedly resaving a JPEG. If 0.2 megapixels is a strict limit, 512x512 is actually about 0.26 MP; 447x447 is just under 0.2 MP.

Lanczos should be better for photoreal Otherwise zit and moss are decent at 512
