30 FPS at csgo, why?

Hello dear community,

Two days ago, I re-set up my computer. Then I reinstalled Counter Strike. Play a day and had about 250 fps + - 20.

Today I go online war disconnect because my Internet was suddenly off (funny way only with me on the computer, mobile phone and laptop still had Internet). Restart my computer and I had only 30 fps constant.

I went into the task manager and took a screenshot because it seemed really strange to me, since neither the computer was busy nor anything else See picture.

Somehow I have not found any visible reason. Vill. Can you help me.

What's inside the calculator you can see in the picture.

Maybe your FPS are set to 30 in the settings? Possibly. Just have a look. Maybe it's a driver problem. There can be different causes overall.
