GPU out of memory when generating larger textures

[EvanDaley]

If I try to increase the resolution at all, I run into "CUDA out of memory". Are there any workarounds, aside from getting a better GPU? Can I run it in multiple steps or over a longer period of time?

I did experiment with upscaling the 512x image, but didn't like that workflow, and I think there would be a lot of value, generally, in being able to render the higher res textures on the first run.

Advice would be greatly appreciated - thank you!

Also, this package is amazing. Really great work!

A new attention mechanism was added in #575 and will be available in the next version. It reduces VRAM consumption quite a bit and may let you generate larger images.
