Just got an e-mail from NVIDIA that I wanted to share with the community:
FEAR 2: Project Origin was released earlier this week. For the best experience, please download the 182.05 beta drivers from NVIDIA.com. This driver also increases performance in other popular games at high resolutions.
SLI for two, three, and four-way configurations is fully supported in FEAR 2. Support has been enabled since January 8th with R181.20, a full month prior the game’s launch.
We encourage you to test SLI and Crossfire in various configurations to see how end users experience these technologies when a new game is launched.
Below are our testing results based on the first level of the single player campaign.
