Big freezes and disconnects while in match

Hello,

After installing a patch (today) i wanted to play but in the first match i was i had some huge freezing issues i even lowered my video stettings and made shure my pc wasnt overloaded. but what i noticed that every time i got a freeze the Usage of cpu and GPU dropped to 0 for few seconds while i was having the game opened. Few days ago it was all working fine exept sometimes had microfreezes.
