Takes place a long time CS:GO on Windows 10.

Recently rolled this game normally comes back after 5 seconds minimum. Previously, both sides occupied the second. Someone from groping can suggest what could be the problem? Very big problem with this problem. Experts, I need your help.

My thoughts: the impression that after minimizing re-downloaded map/texture.
Disabled the built-in PERC card, the drivers are new, resolution gertsovka is the same everywhere. Even the wind changed, the same thing. I suspect somewhere a tick to remove or put.

I don't know what exactly is the problem because I can not determine what part of the forum to create a topic, and I apologize in advance if I missed it please move. Thank you.
