Probably a software issue (background process, driver, update etc). Your antivirus could also been the cause seeing as it affects a lot of games you play. If you just updated the drivers you could try rolling back a set but first make sure there is nothing running in the background or there aren't any updates downloading. Make sure the game is up to date as well and if it still jerks around maybe revert to defaults in NVIDIA control panel (if you've changed anything).
