I have a YouTube channel, and some of the videos I have planned require me to use a screen recorder, but my recordings have been coming out slow and lagging, and I have no idea why this is or how to put them right. I am using OBS 32bit, and when I record I get a message saying that something is overloaded and to check something (I think), but I'm not sure what it says (I will check), and I have no idea if that is relevant to why my recordings are coming out like this. It may be a frame rate thing, but I don't know how to fix that.

I would deeply appreciate help on this subject before December, as there are some reaction videos I really want to have ready by then - I know that everyone does reaction videos, but I really want to do this, as it is on a subject that means something to me.

If I haven't explained my problem well, please say, and I will try to explain it better.
