Suggestion #4:
Avoid getting into the habit of using multiple screen capture types (Windows, Game, Display) in the same Scene. Use only one. When OBS starts up, it goes out and walks scenes and sources lists and creates them in application and Win UI memory. Having too many handles correlating to screen capture types can reduce performance and take up unnecessary memory.
It is best to create separate Profiles according to screen capture type and give them useful names so you can switch to them from the OBS Profile menu list.
For example these are the three most generic ways to do this. Everything you change is done in the properties dialog box for each screen capture type. This avoids having to create tons of separate profiles/scenes/sources for each application/game.
