All GeForce GTX owners playing BF4 should install these drivers, Nvidia says
You should always be cautious about installing beta software, and if it's a mission critical system you're dealing with, we'd advise against running any pre-release code just because you never know what kind of stability issues may need to be ironed out. At the same time, if you're GeForce GTX owner who plans on jumping in the Battlefield 4 beta (it opens to the public tomorrow), Nvidia says it's essential you install its 331.40 beta driver.
The beta driver preps your system to run BF4 with the latest performance updates and profile tweaks. In addition, it adds support for OpenGL 4.4 and adds or updates SLI profiles for several games, including Assassin's Creed IV: Black Flag, Batman: Arkham Origins, Battlefield 3, Battlefield 4, Crysis, Dirty Bomb, Drying Light, F1 2013, FIFA 14, Natural Selection 2, Outlast, Space Hulk, Splinter Cell: Blacklist, State of Decay, and Watch Dogs.
Nvidia also spent some time stomping out bugs with the latest beta driver. For example, the TXAA option is now back when SLI is enabled in Splinter Cell: Blacklist, and if you noticed the GPU clockspeed would not go higher than 405MHz previously, that should no longer be a problem after installing the 331.40 beta driver.
