Resolution and performance impact.

Hey ! This is not really an issue, but rather a question.

When generating square images (512x512) my 3080 can do ~8it/s but when I try to generate 9:16 image like 854*480, my card can only go to ~1.8it/s.

I'm running it on wsl2 on windows because I'm using deforum in a custom program in python.

Is this related to stable diffusion ? Or am I doing something wrong ?

I'm wandering if SD doesn't like 9:16 image generation.

Thanks and have a nice day !
