Hello. After updating drivers (Version 3165) I can't use Quick Sync anymore - video recording application (Mirillis Action! 1.14.3) keeps crashing every time I start recording. No crashes when start recording with previous version of Intel driver (Version 3071) but recording may abort due to random freezes and is not as smooth as used to be, frame drops. Worked just fine before I decided to update drivers for both integrated and discreet cards
