Strange unresponsiveness (The Witcher 3: Wild Hunt)

The problem appeared out of nothing. 50 hours of passage during each battle(while pressing Tab, i.e. changing the sign) the game freezes, but music continues to play, potions/food you can eat to open the inventory/map/journal, etc. Fading, by the way, it is absolutely similar console command testpause if you know this. Sinned on fashion, so we carried the game and put on a new without them. It did not help. Who can faced, prompt what it can be, please.
