Recently upgraded CPU to 5700x3d and game runs we'll only in High settings - ingame

Hey everyone. I upgraded from Ryzen 5 3600x to 5700x3d and the fps is just great! I used to get only 100 fps, now it's close to 200.

But when I set in game setting to Very low the shot registry sucks. Also I noticed the graphic card doesn't get used unless in-game is set to High. I would like to get more fps and don't really care about how the game looks. What Nvidia settings should I use? They're in default now. One of my friends told me leave it in Default, which I'm guessing is not right. Nvidia drivers are new.

Mobo: Ds3h B550m - Updated Bios. Ram: 16GB x 2 with XMP on. AIO cooler for the new processor. Graphic card: 2060Super 8gb OC Windows Game mode - Not sure if it should be On/Off Windows Power settings: High performance.

I understand PUBg is not optimised well, but is there something I can do?

Edit: I don't want more fps!! I just want decent shot registry. Even if quality has to be compromised i don't mind. A balanced setting to share usage of both CPU and GPU is what I'm struggling to find ..
