GeForce 331.40 Beta Driver Released

The new GeForce 331.40 beta driver is now available to download. An essential update for all GeForce GTX users jumping into the Battlefield 4 beta, 331.40 beta promises maximum performance and system stability in the shooter’s pre-release test.

331.40 beta also includes a major update to our NVIDIA Control Panel Ambient Occlusion feature, which allows you to apply fidelity-enhancing, realistic shading and shadowing to games that do not natively support Ambient Occlusion. With a few clicks, you can greatly increase the image quality of your favorite games, and now, with 331.40 beta, the quality of the Ambient Occlusion shading will be significantly higher thanks to the introduction of HBAO+.

Debuted in Tom Clancy’s Splinter Cell Blacklist, HBAO+ is a new, NVIDIA-developed Ambient Occlusion technique that utilizes the latest technologies to dramatically increase the precision, fidelity, and rendering speed of high-quality AO. For further details on HBAO+, visit Nvidia's HBAO+ technology page, and for more info on Ambient Occlusion itself, head here. To implement HBAO+ in a DX9 or DX11 game, replicate the following settings in the NVIDIA Control Panel.
