Nvidia has begun pushing out its second public GPU driver release supporting its recently launched GeForce RTX 2080 and GeForce RTX 2080 Ti graphics cards, version 411.70.

It's not entirely clear what this new driver package offers above and beyond the 411.63 driver set that was released last week. The URL for the 411.70 release notes (PDF) brings up the 411.63 release notes, and while there is an accompanying blog post, it mentions "Game Ready" optimizations for the exact same games as before—Assassin's Creed Odyssey, Forza Horizon 4, and FIFA 19.
