Nvidia has released a new driver (version 295.73), which brings the usual array of fixes and improvements. Among those is a new Battlefield 3 texture fix, which affects those who run high/ultra settings on video cards with 1GB or less video memory. This often results in artifacts and texture corruption, which the new driver fixes. Nvidia patch details state:
Fixes instances of texture corruption/artifacts in Battlefield 3

running Ultra settings and high resolutions).
