nVidia 91.31 video drivers.
In RBR, some of the stages (esp France and Finland) have had visible
borders in the road surface. I don't know when it was fixed, but it is
gone in the 91.31 drivers. I had 81.98 before these, IIRC.
So far a sampling of other games and sims look good - subjectively
performance is slightly better with my 6800 Ultra.
One big word of advice - avoid the standard nVidia download (worst
control panel since ATI CCC), and get the Xtreme-G version and install
the more traditional controls. Available at http://www.racesimcentral.net/.
Clearly they are trying to hide any advanced features from us stoopid
users ;).
