I have Vista 64 running a Radeon X1900XT GFX card and SounBlaster Audigy LS sound card.
I have installed ArmA and when it launches all the boxes tick EXCEPT the last two then one of two things happens.
Either the screen goes black and nothing happens at all (the programme stops responding) OR the programme starts but the graphics are corrupted (they are sort of grey against a black background and running REALLY slowly!.
I have the latest Vist 64 drivers for my soundcard and I have 7.2 catalyst driver loading for the GFX card (I know therer is a memory leak but it should not stop the game from launching).
Can anyone help me please as I know people have got it running on Vist 64 so I am not too sure why it does not work at all on mine - is it anything to do with those last two boxes not getting ticked perhaps??
Please help!
