Hello
Friend's computer got jerks in games after updating graphics drivers.The driver update was for the beta version of Battlefield 1 (when you run it said that you need to update the wood), then jerks appeared in the first 2 games: Skyrim and Path of Exile.After reinstalling drivers (new and old versions), gone in spurts all other games including Company of Heroes 2.From the words of another he had to battle 1 was driver September - October 2015 :).
