Does MegaFusion work on 4096 x 4096?

Thanks for your interesting method which works for many base models. Does MegaFusion work on 4096 x 4096 (based on SDXL)? Directly changing the output resolution will lead to terrible results.

It will be better if I choose the dilation and reschedule options. But there are still some artifacts.

Theoretically, MegaFusion is capable of generating at a 4096 resolution.
However, due to memory limitations, we have not conducted extensive experiments at such high resolutions.
We recommend adjusting the noise rescheduler accordingly to achieve optimal performance.”

Adding vae.enable_tiling() can make your model work on Single A100. Since most previous works support 4096 on SDXL, it will be less competitive If Megafusion cannot succeed on 4096.
