With EVGA receiving all the praise over their SLI Enchancement Patch, it would appear NVIDIA has gotten a bit jealous of the attention and decided to provide a fix for their own products (fancy that huh)
The patch is compatible with any SLI motherboard, and is non vendor specific. It is suggested to be used in conjunction with the latest video drivers 186.18
Patch 1.0 is intended to improve performance with SLI systems and adds support for Anno 1404 (Dawn of Discovery) and ARMA II. The single patch file is compatible with Windows XP, Vista, 7 and works in both 32/64 bit flavours.
