I realize that emulators use up a lot of processing power. I've also heard that screen capture devices use up a lot of processing power as well. I'm using the Windows 10 screen recorder because Fraps is too slow.

Is there any way to make the recordings appear smoother? Some parts of the gameplay footage is fine, while others parts are choppy. I've tried turning off the sound completely. It helped only a little bit.

What other tweaks should I make in order to get smoother looking gameplay footage?

I'm using ePSXe by the way
