BF3: Improved Beta driver from NVIDIA

Nvidia released a fresh beta driver with focus on Battlefield 3 players.

New in Version 285.79

Includes several bug fixes and performance improvements for Battlefield 3.
Fixes cases of irregular performance (stuttering) primarily seen on DirectX 10 GPUs. The fix improves the performance of both DX10 and DX11 GPUs.
Fixes shadow map corruption seen with DirectX 10 GPUs.
Fixes cases of black corruption lines/triangles with DirectX 10 GPUs.

I don’t recommend using Nvidia Beta drivers, but if you are faced to one of the described problems, you may give it a try:
