Have just spotted that Nvidia has released new forceware beta drivers for Vista 32 & 64.
Has anyone tried these yet?
I'm hoping the fix listed as "Increased Total Graphics Memory under Windows Vista for GeForce 7 and 8 series GPUs" helps in Arma especially with 8800 cards.
They have also released 163.11 betas but these seem to be targeted towards the "World in Conflict" beta.
Reports on these drivers most welcome.
