Default [PROBLEM] A bit of Issue with screen recording

Well, So I have been testing some apps by indie developers to review and make useful utilities popular, and support the devs by widening their user base.
The easiest solution for this is, to use youtube. So, I went for screen recording.

Bu there seems to be an issue with it, because as soon as I turn on screen recording(through app or teminal) the screen falls below 15 fps and my recording at the end turns out to be a disaster, and unfixable.

So, if anyone could advice on any solution onto this.

P.S. - I have tried every app that I could find, so no need to suggest any apps.
