I'm very new to the whole "recording gameplay" thing. And there are a lot of things I do not know.
But somehow, I was able to have an idea on what I should be doing.
I've figured out how to use OBS, but I'm having problems when it comes to the actual recording. It would appear that I am having Encoding Overloads.

I tried recording GBA emulator gameplay, and it works great.
I tried recording PSP emulator gameplay, and it's ok. It lags when I record it but somehow it stabilizes when I make the capture screen smaller.
I tried recording PS2 emulator gameplay, and it lags super hard. Sometimes it doesn't even record anything but audio.

I really wanted to play games on the PS2 emulator though.
I'm using my old Laptop fro like 8 yrs ago, and I think that's the problem. My Laptop just doesnt have the horsepower I need to simultaneously play PS2 games and record it.

I'm thinking of buying a new laptop or pc. Do you guys have any recommendations?
Or do you guys think I'm just having problems with configuring either my PCSX2? or my OBS Studio?
Like I said, I'm new to this whole thing and I'm not sure if I configured both my PCSX2 and my OBS Studios right.
