Your OBS screen should ideally look something like this. I set OBS source to Window Capture and "Window title must match" because I'm recording 2 different characters and some games may not register in Game Capture as a source.

Add a crop/pad filter if your game screen doesn't take up the entire window. Exact amounts to crop may vary.

If you don't, you get a slightly jarring letterbox effect.

I used this guide to separate audio so that desktop noises don't get into the recording. The plugin is win-capture-audio for OBS, again.

PS: Animated avatars aren't mandatory, nor webcams. Animated avatars are another subject in itself.
