Nvidia has released another Beta version of Forceware drivers for Windows Vista 32/64-bit.
Nothing significant has changed from the previous 169.09 version, except a resume from Sleep/Hibernate issue with GeForce 8800 GT cards. These new Beta drivers are still "recommended for Crysis" even though there are no "Crysis" changes when compared to 169.09 release.
This Beta driver version is intended for Geforce 6, 7, and 8 series use only. You can download them here.
