Yeah, I realized this shortly after. Now that I do have it installed properly, chunk loading is messed up. It was suggested in one video that if you keep it on multi-core, you simply have to cycle through the options to get it to load, but my problem is that not all the chunks are missing, just some. In a lot of places, I can see very far underground to lava and waterfalls and caves. In others I can't see the middle of trees and hills and such, or a bunch of the ocean is missing. I can still walk around obviously (as these are no world holes) but...obviously this needs to be fixed too. I messed around with a bunch of the settings in options, but I don't understand which ones could do this, since it happened before I'd changed chunk loading. I'll mess around some more, but if you know which setting/s specifically might have done this, that'd be nice.
