The first day of the new year brings us NVIDIA card owners a new set of Beta leaked drivers, the ForceWare 185.20s. One of the main benefits to these new drivers is the use of ambient occlusion which helps enhance lighting effects and reflections.
The PhysX software version used is 8.11.18 and you can use the drivers with GeForce 6, 7, 8, 9 and GTX 200 series cards. Although not useful to any of us just yet, these drivers also bring support for the yet to be released GTX 295 and 285 graphics cards.
You can try them out for both 32-bit and 64-bit versions of XP and Vista via the download links below :-
