I would be interested to hear from anyone running FS9 on Vista 64bit, on my PC i have installed FS9 and the sim runs fine except I have an issue with the textures on the airplanes and scenery especially add on scenery,  being dark, as though some one as turned the lights off, my graphics card is ATI Radeon 4800 series, i have installed the latest driver. As anyone else encountered problems with textures, or am I expexcting too much of a sim that was designed to run on Windows XP 32bit . I would be grateful of any advice

I run FS9 in Vista 64 without any real problems.

My thanks to all  for your replies, I think i will have to live with this frustrating texture problem, the sim works well otherwise, I have found a way of correcting the textures both aircraft and scenery, by adjusting the settings on the display back to default and then adjusting back to customise, this is fine as long as I do not press the Alt key or the ESC key, then the lights go out, FSX works very well on this PC, I also have FS9 on my XP PC runnig like a Rolls Royce, I will live with it, if I ever find a solution I will post on this forum. Again thanks to all who tried to help
