Plutonium

I used to play Black Ops 1 and 2 on Xbox 360 to 2012 to 2015, mainly BO2. I never was able to catch a nuclear, my record was 24 kills on Free for All, but I was quite good enough. I used to get at least 1 swarm and dogs each day and I could easily get scorestreaks. But now playing on PC for the first time I can't barely get a UAV and I'm even playing with a PS4 controller to get controller support but this still not enough and I'm playing like a trash hahaha any tips that can make me play better?

WolflexZ I have a I5-7300HQ, 1050GTX and 16GB RAM and everything is updated.

So one week has passed and the problem still occurs. I played normal for sometimes but the launcher began to crash it again. I already put Plutonium on Firewall exception and also on Windows Defender exception, I uninstalled and reinstalled Plutonium a lot of times and it still crashes. How do I solve? What is the solution for this? I just want to play.

Is there a way to add a server as favorite? There's no such option in the server list and when I want to play on a same server again it's very difficult to find again.

Resxt No, I only have the base game from Steam installed and I downloaded the DLC's, nothing more. And it's completely random, sometimes the game opens up and stay opened for a couple moments, sometimes I can join a server and play a little and it crashes and sometimes the game doesn't even open at all. But today it's impossible to play, I can't even join a server, the client can't stay opened for a minute.

Resxt I only use Microsoft Defender from Windows 10

At first my client was crashing and closing the game without any error warning or message. So I read some people here telling to run Plutonium as an administrator I did that and worked. Yesterday I installed the DLC's into my Steam files and now my game crashes even when I'm running as a administrator, it closes without any message, anyone can help? Here's my Steam files.
