OBS reduces in-game fps. How to fix it?

[Maypher]

I'm trying to play a game and record it at the same time. I have a laptop with an Intel I7 and a GTX 2060 so specs shouldn't be a problem. The problem comes when trying to record. When recording or even having OBS open without doing anything lags a lot the game (dropping in-game frames from 144 fps to 50 fps), this renders the game unplayable. I know the problem isn't GPU overload because when having the game and OBS open the GPU usage doesn't go over 60%. So what can the problem be and how can I fix it?

Use game capture instead of display capture.

I've already tried that and it still shows the same problem.

Play the game in small screen. Then select window capture instead of Game or Display Capture. Run obs as an administrator. Turn GameMode on.
