My game runs pretty well on a single 1080Ti with very rare crashes

Pretty sure this is outright incorrect. From the wiki:

Each Ingredient converts into only one type of Extract, so there is no danger in using the “Extract All Ingredients” button.

And yea looking at the recipe list you’re definitely wrong

I don’t think there’s any reason not to make all the extracts. AFAIK the unextracted ingredients aren’t usable for anything

“Whatever reason” is obviously just trying to cut corners and improve the bottom line with no regard for the consequences.
