New 6800 GT installed with drivers 66.00, the running demo in Far Cry seems
to be blur, I have tried all the settings in the game. During the game the
graphics seems to be OK.

Its probably only a mpeg movie - looks bad here too

Is this normal? I have not tried any other drivers, do the 66.00 drivers
have problems with Far Cry?

I'm sure its normail - play the game - it rocks
