Following the release of the WHQL 320.49 drivers earlier this month, NVIDIA has moved on to their next driver branch, R325. The first release of these drivers, 326.01, was published in a limited form as part of the Windows 8.1 preview, and today NVIDIA is following that up by releasing the first full beta of R325 with the 326.19 beta drivers.

As is usually the case NVIDIA’s release notes mostly focus on the performance of these drivers. Among other things, NVIDIA notes that 326.19 “Increases performance by up to 19% […] in several PC games vs. GeForce 320.49”, calling out Tomb Raider and Codemasters’ racing games in particular.

Meanwhile users on the cutting edge of display hardware will want to pay attention to the fact that this is the first full GeForce driver to support “tiled” 4K displays such as the Asus PQ321Q, which requires support for 2 device “mosaic” mode to properly drive the display at 3840x2160@60Hz. Outside of 3 display Surround modes, this functionality was previously limited to NVIDIA’s Quadro cards as a product differentiator.

As usual, you can grab the drivers for all current desktop and mobile NVIDIA GPUs over at NVIDIA’s driver download page. And thanks to reader SH SOTN for the heads up.
