Panic not mitra the 256 driver from Nvidea displays the game correctly (and heck my grid lines even with the 260.99 driver was almost unnoticable really only spotted it when looking at this thead and examining in game viewing long range at about 3/4 range back .
Ifyou want i can reinstall the 260.99(not many would be using this its only a few weeks snce it has been a certified driver was in beta fror a while) diver and post dxdiag and screenshots??
I spend alot of tme on the Nvidea tech forums posting my frap results and screen errors in aid to try help them find any problems with drivers.I was one of the many guys running there betas back in the time when they where having TRAA bugs translucent Anti Aliasing
