Since Lightroom is utterly unusable without rendering Previews, I am now stuck with generating 2000 Previews before being able to start actual work.
Now the issue is that during the time the Previews render I can't seriously do anything else as the whole computer (pretty powerful) is bogged down by the task.
Ideally I would be able to start editing while Lightroom is calculating previews in the background. But that's obviously not the case—while other apps at least manage to get some CPU allotted to them, Lightroom itself is just unusable.
So I was wondering if there is a way to limit Preview-Rendering to one CPU core? That way I can at least use Photoshop in the meanwhile. Or do something at least somewhat useful.
PS: I am Running Lightroom CC on Windows 7 x64
