I have a slow ISF I converted, I would like it lower it's resolution as it will be scaled down anyhow.
Is there a simple code insert for GSGL/ISF's to lock down input resolution no matter project resolution?
I've been googling around for some time, and am completely missing it.

The shader I'm using is https://www.shadertoy.com/view/lsXcz8

Your software is (insert tall swear word of an adverb here) amazing, thankyou.

Yes, you can use the Resolution module for that. Put it right after your ISF module and it will actually work backwards to render the ISF at a lower resolution.

Bingo! Thank you. That module opens a lot of doors for me.
