Set Far Cry to work in Compatibility Mode: Windows XP. That should ease some
of the problems; I got much better frame rates on DirectX9 games using
Capmatibility mode, Vista uses DirectX10 by default, which is better but
doesn't work with DX9, so it apparently wastes some time trying DX10 before
switching to 9. Or something.
Yes it wil work; if FC64 didn't work in Vista64 the game wouldn't even have
installed. You did run the install for it, in Vista, right? Some people
tried just running off the XP install, and that doesn't work.
