Hey everyone. Hope everyone's doing well.
I record Game Development tutorials to post to YouTube. Recently I noticed that at some portions of the recording, the frame would freeze for a few seconds and then continue.This is an issue for me because at certain times I'm typing code, or maybe showing a certain feature working.
Can someone help me with this?
I understand I am supposed to post a log, so here it is. It is from the very last recording I did, which is the one where the problem occurred.

Code: 
Audio Format
48000 Hz

check your playback and recording devices for "Fast Track" is the format 44100Hz or 48000Hz? whatever they both are, set OBS to that format. currently OBS is using 48000Hz.

since you are local recording change x264 preset to superfast and turn CBR off. next set custom buffer to 0 (its next to your bitrate).

Lastly monitor capture isn't recommended since it can lag a lot at times. also note that you ahve switchable graphics but are stuck using the intel instead of your dGPU since you are using monitor capture. you are kind of stuck doing what I said above.

For recording I use Audacity (Audio) and OBS (Audio & Video). I deleted the audio track from the OBS recording later because I only use it to sync the audio recorded by Audacity. I checked the settings. In Audacity it's 44.1kHz and in OBS it's 48kHz. But how would these affect the video?

Alright, I did all that you mentioned. I should mention, OBS gave me a warning when trying to change the x264 preset.
I haven't tried recording with these settings yet.

Oh I wasn't aware that with Monitor Capture it uses the Intel GPU instead of the AMD. But if I use Window Capture, won't I be restricted to one window only? What if I wanna, say for example, show something in Notepad, and also show something in Windows Explorer, and then switch back to the Unity Editor (the window that I was initially recording)?
What would be the best way to do this?

the problem is CPU usage. with matching autio format the CPU does not have to reencode the audio format with is helpful with low end systems.

the preset change is mainly to let you know that adjusting it will change how log x264 spends on encoding. in this case, we want it to encode less quality (for better CPU usage) but this will not be a problem since the encoder will make up for the "loss" with higher bitrate automatically when you set buffer to 0.

In your case you are stuck using monitor capture because I dont think that there is a way to force the desktop to "high performance" in the driver which would then use the AMD GPU.
