I was testing some bits n pieces last night after a reasonable volume of whiskey. At half 1 in the morning, I realised i'd installed a fresh 7-64 O.S. that was different to yesterdays, with the 320.xx drivers and was running Unigine Extreme with LOD.
So.... if I did that, LOD DEFINITELY works, at least in 7-64
(I had a great night!)
