Same workflow but final image results differ :(

[AlexK98]

Hello,

I open workflow from image generated in late august this year, run the queue and get different results. Why?
Sampler is DPMPP_2M_SDE_GPU, scheduler KARRAS. I thought developers have some refs to compare generation results, no?
Some workflows from previously generated images give more close results, some workflows generate exactly the same results, but some generate very much different results.

Thanks for your suggestions.

I tried several fresh builds starting from 0.3.45. Installed minimum custom nodes packages, replaced torch 2.7 cu128 with torch2.8 cu128, replaced packages like opencv-python-headless and opencv-contrib-python, numpy. Nothing helps. :(
