Witcher 3 and Batman: Arkham Knight free with select Nvidia cards

Both games included with GeForce GTX 980 or GTX 970.

Nvidia has announced that purchases of its GeForce GTX 980 or GTX 970 graphics cards will include a free copy of The Witcher 3: Wild Hunt and Batman: Arkham Knight.

In an official statement, the hardware manufacturer said both games benefit from Nvidia GameWorks, its middleware software suite that brings together rendering, visual effects and physics development modules.

"Both Batman: Arkham Knight and The Witcher 3: Wild Hunt raise the bar for graphics, rendering two very different open worlds with a level of detail that we could only dream of last decade," the company said.

"On the PC, each game is also bolstered by Nvidia GameWorks -- increasing fidelity, realism and immersion."

The Witcher 3's release date was recently delayed by three months but is now expected to ship on May 19.

Meanwhile, the Batman: Arkham Knight release date is set for June 23. Publisher Warner Bros. recently responded to criticism over the pricing of its $40 (£32.99) season pass by detailing some of the content that will be offered to purchasers, such as a prequel campaign featuring Batgirl, character skins and additional story missions.
