I am noticing lag just editing one 20k word section, in a document with three sections of comparable size. Clicking to move around within a document section has a noticeable delay between clicking in the new spot to seeing the cursor show up and start to blink, sometimes a full second. Switching between sections of my book (max 22k words per section right now) can take 2-3 seconds, and monitoring CPU utilization shows a spike to 2-3% for Scrivener when I do that. Clicking within a section only spikes to 0.5% at most, usually 0.1% to 0.2%.
My system is pretty beefy and I don’t have performance problems with other tasks, including gaming, graphics design, and software development with Visual Studio. My system is an AMD 3900X with 32GB of DDR4 and a decent 1TB M.2 system drive, which is where I also save my documents. It should be overkill for an application like this.
I really want to use Scrivener. I know it’s a beta and bugs are expected. I wouldn’t use the beta, but my eyes can’t deal with white backgrounds. My whole reason for buying it and using the beta was to use the themes functionality. This performance issue is very distracting and pulls me out of my focus. There’s no way I’ll be able to use Scrivener full time like this.
Do I need to split my sections up into smaller pieces? By chapter instead of by parts? MS Word was able to easily handle documents of this size decades ago. It did not have the same features as Scrivener, but nice features don’t matter if the program isn’t really usable in its current form.
Edit: A few more system details. I’m using Windows 10 Pro and the 64 bit version of the Scrivener beta. Also I updated the CPU, I had my old CPU listed. I tried both the 32 bit and 64 bit versions.
