I know my question is not related with server/s, but I will post here, because this is community for cs!
When I launch the game (Counter-Strike) with nvidia gpu, I play with 20 fps, but when I do it integrated intel gpu the fps is normal. So obviously the problem comes from the nvidia gpu, but I don't have problem with fps in cs:go using nvidia. Also drivers are up-to-date!
