The GeForce Website now offers WHQL-certified "R331 Game Ready" driver for NVIDIA graphics cards. Word is: "This Game Ready WHQL driver ensures you’ll have the best possible gaming experience in Batman: Arkham Origins and Battlefield 4. GeForce Game Ready drivers also provide performance increases for a variety of different games." This is what they say this does: "Performance Boost – Increases performance by up to 13% for GeForce 400/500/600/700 series GPUs in several PC games vs. GeForce 327.23 WHQL-certified drivers. Results will vary depending on your GPU and system configuration." Thanks Iggy.
