My PC was cleaned recently from dust and other dirts, I've also changed the ventilator.
System is also almost fresh, maybe 2 months old.
The issue appeared after the update, so I don't think that it is my PC fault, also I'm meeting the requirements for the game.
And I'm not alone, look it up on steam community hub, there are other people with this problem.
EDIT: I've also scanned for viruses today, de fragmented my system and runned CCleaner, nothing changed.
