Good morning everyone, I’m new here 
I love Scrivener but… the letters seem to have very suddenly started appearing very slowly on the screen. I type pretty fast but I am having to slow down, and I’m soooo near the end of my first draft of my book, its frustrating.
Anyone know why the slowing down is happening? I have 2 Scrivener projects, I just put one in the recycle bin in case that made a difference. The one I’m working on is 124 KB, is that too big? Help!
I’m on the wrong platform (Mac, not Windows) to offer much help, but I can say that 124KB is tiny—it won’t be that.
I’d try increasing the AutoSave interval to ten or fifteen seconds. Tools > Options > General.

Thanks both
Also if you’re working with the Project Targets open, try closing that–there’s a bug where that’s causing a lot of lag when it updates, which will slow down typing. This is fixed for the next update, but for now you’ll want to just pop open that window to check word count and then close it again to keep typing faster.
Another possible cause could be if you’re working in a very lengthy Scrivenings session, i.e. if you have a lot of documents all loaded together in the editor. Try just loading the single document you’re working on in that case to see if it speeds things up. Alternatively, if you have a really long single document, try using the Documents > Split command to break it into a few smaller sections so you can then work on just the relevant piece without needing to load as large a file in the editor.
Thank you. At the moment, changing the Autosave timing SEEMS to have helped but I will bear your suggestions in mind for future problems.
I don’t really understand Scrivenings, there is so much I don’t know about Scrivener! 
It’s worth running through the tutorial - it will save you a lot of time in the long term. And Scrivenings mode is, to my mind, the best feature of Scrivener (basically it takes all the documents you select and presents them as one long document).
Yes, I did go through the tutorial, I wonder if I’m in the Scrivenings section without knowing it. TBH the tutorial was a lot to learn in one go, maybe I should have done it slower. lol!
It is a lot to take in, especially at first.
I’ve been using Scrivener for about a year now, and in that time I’ve put down over 1.3 million words, and I’m seriously considering redoing the tutorial because I pretty much only learnt what I needed to in order to get my work done, and I just KNOW there’s stuff that I’ve missed, or that I"ll have an “Oh, so THAT’s what that does” moment. I’m sure I’ll pick up the information better now that I have an idea of how Scrivener works and a better grasp on what’s what in the interface.
Thanks to the help here and from Gwen Hernandez (author of Scrivener for Dummies), I now have a Compile of the first draft of my new novel trumpet fanfare. So I’m pretty happy
