The latest Game Ready drivers from NVIDIA, 381.89, launched a couple of days before yesterday’s release of Warhammer 40,000: Dawn of War III. These drivers were the target of optimizations for that game, as well as Heroes of the Storm 2.0, Batman: Arkham VR, Rick and Morty: Virtual Rick-ality, and Wilson’s Heart.
Beyond game-specific optimizations, there isn’t a whole lot of difference between these and the previous drivers, 381.65. According to the release notes, the idle voltage has been reduced in some circumstances, a crash in Sniper Elite 3 has been resolved, and two bluescreens have been fixed. That said, there’s occasionally undocumented changes that crop up.
You can pick up these drivers from NVIDIA’s website, or through GeForce Experience.
